Interesting.

And I can't deny your car looks really shiny...

I think I should at least try Si02 spray before I do anything.

Q: ALSO; Since you seem to know a bit re- car maintenance - are there any products out there that tend to disguise 'slight stone chip peppering' on the sills towards the rear wheel arches. (Road trip to Wales, a degree of speed + dry road salt...!) My car is GT silver.

I've machine polished and coated 5 or 6 cars now. I can thoroughly recommend ceramic coatings. As others have already explained, they have their limitations, but they can also make routine car cleaning much easier and leave you with a much nicer finish. Flies don't stick half as badly is one advantage.

What I would suggest though is looking at other coatings. Gtechniq stuff has a good name but in my opinion the Gyeon Mohs range of coatings is a lot better. I did my Cayman R in Gyeon Mohs and a mate had his F-Type done with Gtechniq by a pro detailer. We then did the same 1200 mile road trip in all sorts of conditions and got the cars in a right mess. On returning to mine we power hosed both cars - my Cayman was a lot cleaner after just a hose down. We then washed them by snow foaming, rinsing and then a 2 bucket wash and again the Gyeon coated car cleaned much more easily, especially the flies.

Worth noting is that most coatings come with a "top up" product. Some of these are misted on to the car dry, some wet and some it doesn't matter. This is worth doing as it tend to maintain and increase the hydrophobic properties of the coating.

It's now 4 years since I coated my Cayman and it could do with being done again (mainly the front end that gets peppered with flies etc but the stuff has been great. Drying the car takes seconds vs a non coated car.
the issue is you still get fall out on ceramic coating so to keep them smooth and easy to wash you have to wax them or top them up with A si02 spay, other wise they feel rough. Also bird st still etches ceramic coats !!

a modern spray keeps your car sealed 100% of the time, every thing falls off easier than on a ceramic coat. (unless you wax/treat the ceramic coating)

also no need to snow foam or 2 bucket wash !!! another snake oil is snow foam !!! it does NOTHING bar look cool for the neighbours and make a mess on your drive/road ! for detailers it makes it look like the £1k detail is doing something !!

rain washes my car it's so slippy !

The main 2 issues with ceramic coats are,
1: it needs the upmost perfect prep as any swirl mark is sealed !! (that's where the cost is, st detail st ceramic coat finish)
2: if you get a stone chip or worse a small scratch, you will have to wet sand the coat off.

wax always will win the concours look and imo offers the best smoothing and best finish but is hassle.

modern Si02 spays seem to be the new king and what I tend to use, offers 2/3 months full beading and takes 10 seconds to do, YES 10 seconds !

SiO2 Liquid Glass is a coating of pure, safe, quartz glass or silicon dioxide (Si02).

in fact I think people with ceramic coats have to also top up with a Si02 coat wash to keep it working right and offer the beading and wash protection.

Some form of SiO2 Liquid Glass is king of washing imo today.

sadly that area is bad on these cars :-( I just use a chip ex product there and dab them in, there is PPF there oem anyway but alass the bit is not big enough !

I am removing the oem bit and going to ask a fitter to just make another bit 2" bigger all round. oem look but bigger should do the job.
I am hoping no more than £150

chipex is good as you dab the paint in and smooth it off with a magic liquid so no raised paint dabs.

Si02 spay has changed my life ;-)

I like a clean car, but don't like spending money or time on cars in those area's, 1st thing I do while others take their cars to topaz and spend £5k is I spend £1k in a tyre shop buying PS4S's

I am a fan of ceramic coats if people want them that's fine, just think they are expensive and you can get the same look and wash ease for a tenner.
ppf and coatings add no value to your car some part ex time. in fact a bad PPF job can detract value as they don't really stop stone hits so just leave a dirty hole in the PPF !

Si02 is a coating I guess but a 3 month one with no down sides. and the money saved buys a set of PS4S's

here is my car after a 40p spay product and my car lives outside + all winter.
This is a 1 bucket wash and dry after 2 months of st on it.

modern products and cleaning are so good, people imo are being ripped off with detailing PPF and coatings.

you can ceramic coat your own car for £49, or you can spay wax your car with some magic st for 40p.

Its very easy looking after cars today.

the spray coat lasts 2 months and then after a few washes when it stops beading I'll spray it again.
wheels took a few minutes to clean every thing just falls off.

people are paying daft money for a clean car !!

NO ppf, NO deatailing, NO coatings and the car gets used and lives out side, what's up with every one !

thank me later but for glass I use :
Dodo Juice Clearly Menthol Glass Cleaner, that is a tenner but even the other half cleans the whole house with it, it lasted a year.
best glass product I have ever used.

I used to spend a day on my cars every few months, was this, machine polish that etc etc , now it's an hour once a month !

best thing I ever did was fit a water softener in the house, clean sink, showers and glasses, and also nice water to clear your car with.

Agree 100% with this. I've been suckered in the past with snake oil products such as snow foam and Swissvax (or whatever name it goes as now). My car lives outside and is driven in all weathers. I polish it twice a year with a dual action polisher and use sealant. I wash when it gets dirty and then top up the sealant when needed.

I have disagree on some points there. Snow foam being the main one. If I powerhose the car then snowfoam it and powerhose it a 2nd time there is a vast difference in what comes off. So it isn't doing nothing. I tend not to let the car get especially dirty and often a snow foam and rinse gets the car looking pretty much clean. There are plenty videos out there that show the assertion that it does nothing to be incorrect. After winter it is also good at getting those small sandy particles off the car before you touch it. A lot more hose off post snowfoam than pre snowfoam. I've tested this theory myself so I know it to be correct.

The top up for my coating involves a quick misting of spray over the freshly rinsed car before it is dried. So maybe adds about a minute to the wash process. I have no need to wax the coating. I've also never had any etchings from bird mess, although a couple of flies have left slight marks.

All coatings and protection have their pros and cons be it PPF, ceramic, or Si02. You need to find the product that suits. If you have a daily left in the street or a garaged toy that never sees rain then the solution wont be the same.

I have had plenty stone chips on my car. I fill them with paint, wet sand if needed and polish. The Gyeon coat doesn't cause a problem with this, though I mask around the chip so I'm not polishing more than necessary. And as you know the only proper way to get the pain right after a stone chip is a respray anyway.

Coatings are horses for courses. Best is to figure what you want from them, what you're prepared to pay, how much you are or aren't happy to top them up etc and then make a choice.

Sounds like you used a crap one or didn't mix it to the correct strength. If you use a good one like Bilt Hamber's product 'Auto Foam' and mix it correctly, you can literally see the dirt sliding off the car.
Less dirt on the car = vastly reduced chance of swirls = no need for correction

si02 spay, dirt don't stick to the car, it just falls off.

Snow foam is the worse product I have ever tried, a jet wash does the same thing sans foam on a protected car.

as I said rain cleans my car...

Some very helpful views here - much appreciated !!!

Q: Whilst we are on with all this knowledge... By any chance, does anyone know of a - ppf type product - that could change my LED headlights with clear lenses - to make them look like LED headlight lenses in black headlight option ?

Thanks.

My wifes car had Gtech ceramic glaze put on it (by a ph'er with a detailing business), 3 years ago when new. It still looks new when cleaned and is very easy to clean.

I liked it som much that I have just hasd my Evora done by the same guy but using IGL Kenzo which he recommends as being better than Gtech. The car has come out beautifully. Its my daily driver so I think it will benefit from the treatment. Its definately as shiny as I could ever make it.

The water beads very well and so far bird droppings have been a doddle to remove.

The reviews reckon IGL Kenzo comes out with a very warm finish a bit more like wax, but its hard to be sure.




On the second pic you can see my wife's Octavia that I had done, in that pic it hadn't been cleaned for about 3 weeks (750 miles) of rural use.

A jetwash doesn't do the same thing, if you think it does, you used the snow foam incorrectly or it was a bad product (and there are a lot of bad ones available). Like I said, Bilt Hamber Autofoam is the one to use.

From what you're saying you would have a perfectly clean wash mitt and bucket of water after washing the car. If that's the case, then I want to know what SIO2 product you're using! Because neither GT C2V3 or Megs product I've forgotten the name of get anywhere near that result, at all.

GTC2V3 is not a ceramic sealant to the extent of te professional ones. Its more of a home application quick wipe over type top up. I use it as a detailing spray. It doesn't get the paint as slippery as the professional stuff.

Many snowfoams are rubbish, so I agree, the Bilt Hamber one is good, I use Blizzard snow foam, and although its expensive, a little goes a very long way.

One could question whether it's wise to clean a car with softened water - with the salt in it. Also didn't think most water softeners were connected to the mains taps like a hose (+ drinking water tap).

Curious how this spray (for the car) works and how often it has to be applied - you mention every few washes... how many & is it a pressure washer which clears the coating?

OP - as others have mentioned think a lot depends on how you like to maintain your car & how much time you want to commit to doing so. I also think the colour will dictate a lot of the choice. Black Cayman myself & the ceramic coating makes washing very easy. I like the car to look good, and the coating definitely helps without spending hours cleaning it - although sometimes I will do so! Having my time again though think I would rather pay an independent to do it than the garage I bought the car from. Nothing against them; the detailing was very thorough & I was happy with what I paid for it, but after a couple years the protection is not as good as I hoped, despite the 5 year guarantee.

I know, but the poster i was replying to was talking about a 'sio2 spray' (costing 40p) not a professionally applied product. Hence my doubt.

I agree with your doubt. Idoubt a spray for 40p woul dgive you the longevity or benefits of a ceramic seal.

I was initially scptical, but after having teh Octavia done, I am a convert.

After a mucky day last winter in Wales, my car and my friends 570 were plastered in mud. Used snowfoam twice. It really did get alot of dirt off. What i noticed was that the Mclaren had PPF and then ceramic coating, the dirt just slid of, where as mine as just PPF and it took more work to get the dirt off.

I only used ceramic coating for my wheels, calipers and exhaust tips and the dirt does come off really easily. However I did PPF the front end, sills and rear bumper/1/4 sections. When i sold it the PPF had holes in and was pretty much destroyed. It was pealed off and no marks on the paint, saved me a respray, and was cheaper than a respray too. Some PPF places are a rip off. I will always PPF my cars as I drive with friends on trips and they just get peppered.

Nope tried multiple products and even bought an expensive snow foam nozzle for my jet wash. I found that all it did was just fall straight off the car as the car either didn't have enough muck on it or the sealant/wax didn't allow it to sit on the car long enough.

The only product that I've found that works properly is Autobrite Magifoam. However you have to use it neat to be effective which means it will also remove any wax, sealant from the car. I stopped using it on my car and just used it on my wifes Audi. Its a great way for detailers to justify their prices because it looks impressive the first time you see it.

That doesn't sound right. There can be issues if the car has a ceramic sealant but its not a problem I see with either of the sealed cars using Blizzard or Bilt Hamber. The Blizzard uses about 20 ml of liquid to a 1 litre snow foam lance bottle, so its pretty well diluted and it still stays on.

Take it back and get them to pay for someone to do it properly
