If the chrome is adhered well enough, you don't have to remove it to powder coat...just rough it up a bit. I think Dutch guy is talking about prepping to re-chrome. VERY dirty, and very illegal in most places. Hey Joe, most of the powder coat salesmen I've seen, quote 400 degrees as their products curing temp; no problem for any alloys I know of. Don't thing you'd even have a problem with the wonderful, Chrysler plastic chrome wheels (300C, trucks etc.) You could do one wheel at a time in a kitchen oven... a big one.
