IMHO, he was mistaken. Ive been told by a number of people on powdercoating forums, as well as the guys that run the stores, specifically for valve covers, to outgas. So, I dont know who is right and who is wrong, but I did notice a difference in the metal after baking it.

Either that, or the cover is cast aluminum (which I think it is )
The valve covers are cast AL, so is the intake manifold. Our X-brace for example is extruded as one sheet of AL, and then cut into it's final X shape. They do not outgas them, but the valve covers have to be outgased.

Yup, thats what I figured. So your guy was right. And so was I. Valve covers pit like crazy if not outgassed.

Jeff, I sent you a reply in your email.

Sweet... I did my 03 wheels at our shop a couple months ago. Experimented with Copper color,.. probably redo them next spring to different color,.. just not feeling it. Only problem with our shop is the oven is big enough to bake a car in,.. so its quite expensive to do a few parts.

Nice work. Did you strip the rims, or just coat over the clearcoat? If you stripped them, what did you strip them with?

So does the powder 'melt' when it's really hot? i can't get my head around just spraying powder at something and just having it stick.

When you first spray the powder, the charge makes it stick to the metal. It you touch it, it will come right off however.

When you bake it, all the powder melts, and becomes almost like a glass/epoxy coating. Once the powder cures, it takes 2 times the temperature to melt it again. They are basically, TINY particles of either epoxy, TGIC, or urethane that melt and form one giant jacket on the part.
