I never really answered Fisherman's question on touch up of powdercoat. When they make the powder they mix the color, curing additives etc it is in fluid form just like regular paint. Then they dry it. Some companies, Cardinal is one of the biggest, will set aside aerosol cans for touch up. That way you have almost an exact color match... however, when curing, the different temperatures and length of curing times may vary some colors, white is especially sensitive to change.

If you don't get an aerosol with the powder you have to try and match the color, just like in auto repair, which can be a pain. Standard colors can easily be matched and used in touch up. Powdercoat is a bit more of a pain to sand away and repair scratches or dents.

I would recommend using gillespie for most of our work. I'm doing powdercoat just because it will be a great advertisement and it is easy for me. The powder color I have matches that AJPWWII chip in the previous post.
