That's a lot of cable!

You might remember I went the other way and installed an aftermarket Sony HU. Like you I've never really been a fan of aftermarket stereos, but I do really like CarPlay and find that I miss it when I'm driving a car without it.

The front mounted USB port isn't ideal, but I liked how Sony hadn't used shiny plastics, and with a dark wallpaper I don't think it looks too bad in the cabin. Curiously, the aux input into my OE non-Bose stereo (Clarion) always hissed a little, and the sound quality through the same speakers was much improved by moving to the Sony HU, but I didn't have any external amps to worry about.
That looks quite nice with the black plastics, so I can see why you kept it. If you want a free reverse camera by the way, just let me know and I can nip mine in the post. I've cut the wire, but I can easily solder it back if you wanted it considering you have a screen?

You could always go down the route I'm going down, and that's turning the 12v into a USB and 3.5mm audio. The USB would plug into the rear of your radio (assuming it's got a port for it), so you wouldn't have to use the front one. May tidy things up a little, but it doesn't look too bad, especially with what you use the car for.

I do find myself looking back over your thread to see what things I can do...

Thanks for the offer, I fitted a camera not long after adding the HU. I went down a bit of a rabbit hole printing a replacement for the blanking panel in the boot where a keyless entry sensor would sit on US models...

https://www.thingiverse.com/thing:3367086

It's a bit silly in an MX5 and I never really find myself looking at it when reversing. You won't miss yours!

I think you'd be horrified by the state of my paintwork if you saw it in the flesh. I've actually grown to quite like the way it's covered in small scuffs and dings. Every other car I've owned I've stressed over keeping it perfect, paying out for smart repairs or paintless dent removal after every car-park ding. Not worrying about stuff like that is quite liberating. Track days haven't been too kind to the paint on the front bumper either.
I thought it would be great having a camera, but even when it was in the car I felt uncomfortable looking at it - it's great for a big car but not really much need in an MX-5. I'll definitely be putting in some reversing sensors mind, so that'll be soon.

I know what you mean with the paintwork. I'm normally a stickler for good condition paint, but I haven't washed the car at all or even vacuumed the interior. It's still got dog hairs from the previous owner's dog in the passenger footwell. Even so it's quite nice to go for a blast and not worry about it. I say all of that, I love the restoration process of a detail and seeing how good the car can get. But I'm not one for keeping it in the same condition day in day out. With the Porsche, I detailed it to an inch of its life and it looked like new, but I got it filthy, had scratches from leaves, gravel etc. I gave it a quick decent wash now and again but I didn't mind getting it dirty with the odd scratch here and there because I knew that I could get it to perfection if I wanted. It'll be the same with this, detail it once, use it for what it's built for afterwards.

Got round to fitting the aux port on the car. I was going to remove the original 12v port and move it to the cubby holder, but I didn't for two reasons. First is that the hole is already there and accessible on the cubby holder, so it would be easy to install rather than trying to remove the original 12v port. Secondly, the phone can be closed away in the center console whilst plugged into music, rather than wires dangling around the gear stick area.



I plugged the 3.5mm/USB port into a 3.5mm female coupler, then into the Bose media connector.



Looks very tidy and quite out of the way.



The wire was (tidily) fed behind the radio with the rest of the wires





And there we have it, AUX input on the original Bose system. I've got a very subtle phone holder (currently tucked away under the steering wheel) that goes into the CD player for my phone if I need to use GPS, so I've now got all of the functionality from the Pioneer head unit, without any of the mess.

Next up is to wire a hidden 12v socket that has the USB plugged into it, so you can charge the phone from the same port. That'll be it for the in-car equipment for a long while.

I'm still waiting for those two days to detail this car. I've got the rest of the day today and tomorrow, so I'm planning on going out shortly to wash/clay the paintwork in prep for polishing it tomorrow or Monday. Hopefully.

Had time to give the car a thorough wash today (not the interior). The exterior, engine bay, door shuts, boot runs and wheel arches were all scrubbed to ensure it's nice and clean for the detail, when it comes to it. If I drive it between now and then, it won't take much to get it back to this as so much mud and dirt came off the paintwork and crevices.







Gave me a good idea of what the paintwork is like. Swirly and scratched pretty much all over. Nothing I can't sort, but it's going to be a challenge.



There's not much in terms of stone chips on this, which I was quite surprised with. I heard that the black cars are notorious for stone chips due to their white primer, but there's very little. I'll sort out the ones that are here on the detail.



Plastics aren't faded and there's no sign of marks or screwdriver gouges.



The wheels definitely need a refurbish, but I'll be doing these myself.

I did my Celica's alloys myself, and they turned out great:





They were multi-spoke and are quite similar in terms of structure to these. Same size, too. Thin spoke wheels are far easier to refurbish as the paint builds up on the surface and makes a lovely even finish.

After I did the paint work, wheel arches, door jams and boot runs, I finished with the engine. This was of course a daft idea, and something which I should have done first due to dirt running on the paintwork afterwards.













Engine de-greaser and dressing. I always like doing an engine, it's a big challenge with the restricted access, and it always comes up good as it's not been directly exposed to the road, so parts normally come up great.

If anyone's interested, here's what I've used:



AutoFinesse Eradicate for the engine de-greaser.



Agitate the whole engine bay with a brush and give it a quick hose down afterwards. Put the hose on a more 'mist' setting and give light squirts. The aim here is to remove the de-greaser and dirt, not to completely soak everything. With a damp towel, remove the rest and let it dry.

When it's dry, apply this:



AutoFinesse Dressle.



Coat it and let it sit for 20 minutes as shown above, then wipe to coat the surface evenly.

I'll most likely refurbish the wheels and paint the brakes next, then the interior, then the paint correction. It'll be nice to finish the paintwork and know there's nothing else to do.

Ha! I quiet like it. Didn't at first but warning to it. I'll keep it for now, but when I start improving bits and bobs in the future I may replace it. It's in perfect condition.

That's interesting about the stereo mind...

Today was a good day to do the alloy wheels and brakes. The sun was out, which is perfect for painting wheels as it helps them dry. The whole thing took a couple of hours, and cost very little.

The aim of this wheel refurb wasn't to get then perfect but far more presentable instead.

What I used:

- Can gun (essential to not 'spit' from pressing the nozzle on an angle)
- Playing cards
- 1x E-tech primer
- 1x E-tech silver
- 1x E-tech lacquer
- 1x Hammerite paint with paint brush

The whole thing is roughly £30 to paint the wheels and brakes. It's not perfect, but it's far better than what it was, and for the price I can't complain as if I ever curbed the wheels, I can do it again with the same process knowing the paint would match.

Here's some shots of the worst areas of the wheels











Some of it is rust, some of it is bedded in dirt that wouldn't come out with a simple wash.

I wet sanded and dried the inner wheel barrel. Again, not perfect, but it got most of the marks off.



I started to rough up the faces of the wheels. This was done very quickly as I didn't need to rough up all areas. The paint builds up in the corners of the wheels, so it's the main faces that need roughing up. I also used playing cards to mask the tyres.





Two coats of primer, then onto the paint



Then multiple coats of lacquer to bring it to a finish









While the lacquer dried, I painted the brake calipers, hubs and disc edges to neaten them up. Any paint that went onto the disc will quickly be scrubbed off by the pad.





All done













Ignore the high ride, it was only then taken off the axle stands.

There's still areas of 'bumpiness' from where the corrosion was, as I didn't flatten the areas back prior to painting. To be honest I wasn't bothered by it, as silver on silver is better than rust on silver. The main thing was, the whole thing actually cost me nothing as I had the equipment and paint already. It was a free wheel refurbish, as opposed to spending hundreds of pounds on powder coating, when it's going to be driven and not entered in any concourse compotitions.

Next up is the paintwork, then interior.

It actually took me two and a half hours to hoover this car. The amount of dog hairs was beyond belief. What you can see in the photos is nothing to what was under the seats and down the sides of them. Honestly, where the belt buckles are were just full of hair, you (and I'm not joking here) couldn't even see the carpet. The dog hairs had weaved themselves into the fabric of the carpet, so it took a lot of brushing and hoovering to get them to move.

They were vacuumed and shampooed, and turned up great.

I'd love to, but I stopped detailing for customers a long time ago. I have thought about doing it again as one-off's, so it's not a 'no'...

The interior is clean! I've not given it a coating of dressing yet, so it's just bare plastic at the moment.



The amount of dirt was... surprising.



The pad on the right started like the one on the left. All I've done is wash the interior plastics with interior shampoo. That's not even the seats.



Nevertheless it's come up very well.

Here's a few photos of some close-ups after some wok with the detailing brush in every tiny groove.









Not sure what to do about that gear knob. I've absolutely love a wooden ball, in a very Carrera GT style, like this:



I'll keep an eye out. In the meantime, I may sand and polish this back up.

Whilst masking the car up to start machining the paint, I removed the side indicators. One is more faded than the other, and I'm not sure I'll be able to polish this back up being so small, so I'll look for a replacement.



I started the bonnet and front bumper, but only managed one pass on each as this happened...



Another one is on the way, but I may not have time for a few days to continue with the paint.

Either way, the first pass is promising.



You can see the line where I've polished the left hand side.



That's better than the scratchy mess before.

I did the headlights while the bumper was still on the car to see if I could get away with it. Turns out I can.



Original



Sanded



Machined. The colours are from the CP lens of the camera.



I really want to drive this car, but as I've clayed the paintwork I'll have to ensure it's spotless again if I do before I continue with the machining.

Okay some of you might think I'm daft or insane, but I'm going to make my own gear knob. I love the idea of a dark, mirror-finished wooden ball of a gearknob. I think it would go well with the black interior, would look quite 'classic' in an odd way, and would feel fantastic. I'll be keeping the original, just in case I don't like it.

Basically, I'm ordering two relaxing wooden balls:



And an m10x1.25 thread insert:



Drill a hole, pop in the insert, job done. £6 for the balls, £2 for the threads, gives £8 for the project. The balls won't come for a few weeks as they're from China.

If it goes well, the balls come in pairs, so I could make a second for someone if anyone's interested.

Amazing freshen up on the interior - i wish i had the skill/patience/product knowledge to be able to do that on mine.

personally, i don't like the wooden gear knob - there's nothing wrong with it in isolation, but i don't think it 'fits' in that interior. there is nothing else even remotely wood, let alone the same colour..

Dunno.. personal preference obviously, just from me, it's a no.

loving every other aspect of this car (and thread) though smile
I can see your worry, but I'm thinking of the Carrera GT's interior and how it pulls it off:



You may be right though, it could look terrible... will keep the original just in case and will polish it up in the meantime.

Lovely car and nice job in getting it back to fine fettle. I've been really drawn to these lately so think I might take the plunge soon enough.

Anyway, I really only wanted to post this link to a few documentaries on the MX-5 from the NA to date. Some great interviews and some better technical geeky stuff. Wish there were more documentaries like these!

https://www.youtube.com/playlist?list=PLr-mTF1DFa-...
That's brilliant, thank you! Will sit down and give them a watch shortly.


We took a drive through the valleys, over the Rhigos mountains, up through Brecon, on the B4520 and up to Builth Wells in mid-Wales today. Beautiful drive!







I didn't seem to see any stone chips when I was cleaning the car, suddenly after a long drive it's got quite a few. It must be the polish in the chips as for starters, it wasn't like this up until today, and I only just started the first stage when machining it, so I'll have to go over it again with the Megs 105. To be honest, black glaze does wonders under wax to hide stone chips so I'm not too worried.



I'd drive all the way there for the bacon benedict any day.





When we got home, my wooden balls (snigger) and thread insert had arrived!



The Chinese ones were resin and not wood, so I had to cancel them and buy some more off Amazon that were wood. £8 to give this a go in total, so it's worth a try.

The aim was a bit of a homage to the original MX-5:



And to the Carrera GT, one of two of my favourite Porsches. The other being a 964 Turbo.

I practiced on the lighter one, and finally did it on the darker.



Bit messy, but it's underneath.



The thread was a tight fit, so I had to hammer it in, then superglue finally bonded it in incredibly well. It isn't coming out anytime soon.



And finished





I quite like it, but I'm still torn. I love the dark wood against the black, and I love how it feels. I'll give it a try and will see how it goes.

Decided to go back to the other lighter coloured one of the two that I had. I've since coated it with lacquer, and the finish is fantastic. Perfectly smooth, good to hold and I think it works quite well.

I'll be restoring the original MX-5 gear knob anyway, as I may end up changing my mind.

I've got my new Chemical Guys orange hex logic pad, and some more masking tape. Tomorrow is also looking very cloudy and dry, perfect for machine polishing and waxing.

Finally! It's looking like tomorrow will be the day that the car's cosmetic corrections are finished. Here's hoping the weather will hold off...

Thanks for the kind words both. Eibach springs are on the list of things to do, though I've been contemplating KW springs (their ST line) for the same price.

The car's been detailed, it's finally finished. I'm absolutely spent, but it looks fantastic. Photos to follow later this evening.

I've replaced the windscreen scuttle gromets before I started the detail process. Surprised how cheap these were. The old ones were totally shot, so it was about time.





Anyway, onto the detail.

A lot of hours went into this car to get it to this stage. Fixing the suspension, rebuilding the caliper, removing the horrendous wiring, refurbishing the alloys and finally a full detail, including a two stage paint correction, headlight restore, exhausts, and a full interior job too, including dressing for all plastics.

Lots of work, but it's paid off. The car is exactly where I want it to be for now, and that's back to what it should have been like.

The exhaust was first up





1500 grit wet and dry, followed by Meguiars NXT metal polish. This is the only 'progress' photo as I couldn't be bothered to take any during the detail as I just wanted to crack on with the job.

Hope you enjoy the finished result. I forgot how much better polished gloss black looks compared to metallic black.





























In total, the cosmetic jobs consisted of:

- Replaced gear knob with gloss wood knob
- Roof mould removed and hydrophobic coating added
- Refurbished alloy wheels
- Painted brake calipers, hubs and guards
- Clay treatment
- Two-stage paint correction
- Carnauba wax
- Wet sand and polished exhausts
- Interior plastics deep cleaned
- Interior plastics dressed
- Carpets thoroughly vacuumed
- Carpets shampooed
- Leather cleaned and treated
- Headlights restored
- Glass polished
- Rubbers treated
- Engine bay detailed

The main thing is, this isn't a show car. It's not going to enter any concourse competitions, and I'm not going to clean it every week. It's going to be driven and enjoyed

However, when I do wash it, it'll be washed correctly as to make the finish last. You should technically never have to polish a car and should only have to wax/protect it, as 'polishing' is the process of correcting issues. For as long as it's protected and washed correctly, it'll last. It was the same story with the Porsche, it received one big detail, and years afterwards didn't see a single swirl/scratch on the paintwork. This car is going to be used frequently and on track in the future, too.

Now to drive and enjoy it. I still need to replace the chrome indicators and a few other bits and bobs, so I'll be tackling those this weekend.
