Chassis clean up.
Discussion
Advice much appreciated. Waxoyl is hiding flaking chassis paint on top of rust in a few places. What's the quickest and most effective way of getting all this crud off and taking it down to bare metal before treating and re-coating? Damn waxoyl is a bugger to scrape off. Hate the stuff.

It's the other side of that triangular plate (the topside) where the devil hides!
Quite right! Would love to be able to lift the body and get to everything evil lurking on the topside of the outriggers. Just searched the forums on what this involves and it looks like a right PITA. I've done this horrible job several times now. I spray on a good degreaser (I've found Comma Hyperclean is very effective) all over the chassis and suspension, leave for a bit and use a pressure washer to get it and most of the old wax off. You'll still end up going over it all with the degreaser and lots of rags by hand, but it gets 90% off.
I'm sure a steam cleaner would be effective too, but I don't have one and wouldn't trust others not to avoid electrical connections!

International paints GTA 220 thinners will basically shift anything. Use with care, wear suitable heavy duty gloves and use in a well ventilated area. [leave the garage door open]
It makes a fantastic degreaser and it will melt waxoyl with ease.
Not cheap but good stuff.

Another good alternative would be cellulose thinners. This should also melt waxoyl quite easily.
I too have a personal opinion on waxoyl, it is absolutely sh
te. Some people and dealers use it to hide a multitude of sins.
You can imagine the scenario .... a tiv owner, his car now a couple of years old, takes his pride and joy for a major service. He arrives back at the TVR dealership, and is told......" Sir your car has some very minor surface rust on the chassis, so we
would recommend covering everything in waxoyl. It is fantastic stuff and you will never have any problems like this in the future."..................Bullhit.............what they really mean is......... the powder-coat has started to flake [on a 2 year
old car] and the dealership needs to hide this fact.
12 months later at the next service......." Sir we recommend that you have waxoyl spray applied to the chassis at least once a year, to ensure no "surface" rust problems in the future.".........2nd load of bullhit.....................what they really
mean is...........................let's keep spraying this shte everywhere and no one will be any wiser

With the underside looking like this the top will be pretty much shot so I have to say there is not much point bothering to clean and repainting the underside.Steve

All fair enough but like I've mentioned before, what about getting a full body off chassis job and the people who do the work then waxoyl the chassis. How would you feel about that?
If it was my car i would be furious. Why spray waxoyl everywhere on what should now be a perfectly painted/or powdercoated chassis.I did a full body off chassis repair on my car in 2010 and it still looks like new. no waxoyl anywhere.
I did paint mine with 6 coats of 2-pack epoxy paint rather than powder coat so thats why it still looks good.
Unfortunately have neither the time to do a full body off job myself, nor the money to pay someone else to do it. Talking several thousand pounds aren't we? 
And I agree with the previous post: I'd be furious too if the chassis was cleaned and painted/powder coated and then waxoyl was blasted all over it.

There is nothing better than seeing that white chassis underneath the car and also something quite satisfying about having done it yourself.
This was my effort last winter over 3 months, slowly stripped the parts off, de-caked the chassis of the hideous waxoyl, cleaned back any rust areas, treated and then 2 pack epoxy.
Wouldn't want to cover this up now

I replaced all the bushes with oem "metallistic" type and had all the wishbones blasted and powder coated. They came up really well and you'll be surprised what a good powder coaters can achieve.
I also replaced the discs but apart from that it was a case of dismantling, cleaning and then re-painting the parts with a bit of TLC.
All the work was done with the body on the car and no lift. With a bit of perseverance and some ingenuity it's surprising what access you can gain to the majority of the chassis and how much you can clean and then epoxy mastic.
Obviously it would never be as thorough as a full body lift and I will admit the outriggers had been previously replaced but they were caked in the waxoyl stuff.
All clean now and will get back under this year for any touch ups if needed.
