had a look on wikipedia and it says 98% sulphuric acid and somet called methylene chloride will budge it, some on ebay funnily enough, lol.. and not too expensive

just wondered if anyone had any clever tricks like brake fluid or somet ?

:)

Nope.
Chemical dip, sand blast or physically buff/grind/sand it off.
That's pretty much your options.

Clean them up first then paint stripper, sand paper start with 400 working your way up to 1000. then Dremel tool to polish the lip. Acid primer, Filler primer, Colour you want to spray it. last clear coat.

It take about an hour a alloy to clean them and about 2 days to pant and let it set in ETC ETC.

well thats the way iv done it in the past.

wasnt to bad, took about 1hr to 1hr 20 to do all four, and all i used you can see here,...
the trick is to apparently tap them to get em started undoing, but most i managed with steady pressure.. very suprised after reading soo many horror stories

Are you sure they are powder coated?
They look like they are painted to me from that pic.

hi ess_three

i was fairly sure they were powdercoated as where one is quite badly chipped it looks very thick like it is powder coated but i guess it could be painted,  maybe worth trying somet to strip paint first see if it gets to it? what would you use if it was paint? nitromours?

cheers

Powdercoat doesn't generally scuff like that...it's too thick, so it just flakes off in lumps.

I'd try Nitromors and see if it bubbles up.

To me, those wheels look like they are still in the standard painted finish.

Well had a try with nitromors and does shift the paint, not powder coating,
However after about 2hrs all I've stripped is a inch around one wheel and a few bits on another, so thinking about looking for a chemical stripper to get it all off, don't mind doing the lips my self cos won't be too hard, a lot of paint off on some already, just need stripping and sanding, may polish now,  :undecided:

So anyone know of anyone local to Stockport, Manchester area that would strip em for me? Don't want a refurb, just the stripping doing..

Cheers

Can you not find a local company who do Chrome Plating ??  They will dip them in the acid they use to clean the stuff before plating. This would be relatively cheap. Many years ago I used to do Chrome Plating and this process takes about half an hour and strips everything back to where you want to be  :cool:
