Cleaning a chassis
lsdweb - 6/10/08 at 06:01 PM

I've just bought a second hand Westfield chassis which will need some minor repairs and mods (different diff etc.).

I want to strip it back to bare metal - what's the best way?

Powder coat can be dissolved by this special stuff from Frosts.

Paint is just paint stripper. Even a high powered water jet would suffice (without getting into the silicosis risks of sand blasting)....

we charge £180 to blast a chassis using aluminium oxide for comparison(build a car for £250)

ooh, never thought of that one... you'd need to make sure the tubes (it they get wet inside, which preumably if its already built it will have some holes in it some where) were completely dry inside though...

Quickest way I found to strip powdercoat was to use an 80 grit flap disc in the grinder being careful not to press too hard. Wizzes it off without firing metal hair into your legs like the brushes. Lots of dust, so good mask required.

If cash were no object I'd get it blasted professionally by a reputable blasting company who wouldn't just chuck powdered bricks at it.

I second that. Either that or nitromors and wire wool. youll have to wash it off, and it makes a bit of a mess. Rubber gloves, eye protection and a rubber apron are a must though! - As is keeping the kids out of the garage while you do it!!
