I just powdercoated the NOS chrome valve cover I had in the FOR SALE forum, which had a little bit of rust pitting on the surface. I glass bead blasted it, then coated it in Semi-Gloss Black for KensAMC over on the www.ifsja.org
I had to change the way I am spraying powder on sheet metal parts, where it's hard to get the powder down into nooks and crannies. My spray method mod worked GREAT on this valve cover. It turned out REALLY SMOOTH!
