Removing triple plated chrome
I'm trying to strip chrome, nickel and copper of a cast aluminum part with a sisal wheel and greaseless compound #80. The process is very slow going. When I do finally get to the copper/aluminum layer the surface is uneven. Alot of heat is generated in the part. Overall I'm not happy with the progress.
I've tried sandblasting, but it is very slow too with my sandblaster. I can't strip chemically because it will attack the zinc in the part. Any suggestions?
