Well I can tell you your stone knives and clubs don’t work on powder coat, paint it does, but powder coat lotsa luck. I was able to strip 3 units that retail for $130ea. and one unit that was $95. Being somewhat delicate and having a lot a structure it is not worth it to do it any other way. The blems happened as they were coming out of the oven and of course on the top side that the customer would see. It’s impossible to put another coat over unlike spray paint so the only real solution is completely strip. In this case I‘m glad there is an alternative that works and luckily I only messed up 4 in thousands of pieces I've done. Not bad.
