How do you strip chrome?

<< < (2/4) > >>

Can`t you just take the shine off and paint or powder over the top  ???

If it was an even covering of chrome that would be fine.
Most of the chrome's removed, but there are patches and streaks of it left.
It would look bad with paint, you'd see the lines and bumps underneath. Powder would probably cover it and give an even finished surface.

I'll give it a try on a small area with wet 'n dry, see if it comes off.
It's a GT frame, were they powdercoated originally? I'm probably being way too fussy, there's dents to fix first :)

leave the chrome on

you can powder straight over chrome
or rough it up and spray over it

I concur with TheRuler. The are 4 ways pwder coaters work, each getting more expensive:

A. Top coat only
B. Zinc / Iron phosphate to clean the metal and form a crystal rust barrier + Top Coat
C. Zinc / Iron phosphate to clean the metal and form a crystal rust barrier + Etching primer + Top Coat
D. Grit blasting + Zinc / Iron phosphate to clean the metal and form a crystal rust barrier + Etching primer + Top Coat

A lot of powder coaters are not too good at handling primers - they tend to over cook the paint and then the top coat peels off. I would get it blasted, zinc phosphate dipped (not iron) then ask for a good thick top coat.

I get a lot of powder coating done for my business - frankly the reason powder is used is they (the companies) can employ less skilled people (and it does go up the tubes). If you want a truly great finish simply go to a local car sprayers and get some 2 pack. Its rock solid and they will have a low bake oven - they will have a wider range of stock colours left over from previous jobs. Powder coaters tend to work with a smaller range of colours.

Getting back to your point - don't worry about the chrome, if you don't want to get it blasted then just rub it down. If you do rub the frame metal it doesn't matter. All you need to do is key the metal and have it clean - just use a medium wet and dry paper.

will powder coat cover with a smooth finish if the chrome is flaking or pitted?
