I bought the Powder Coater’s Handbook from Eastwood (which REALLY needs a lot of editing, I might add). Having read it a few months ago, I didn’t think I needed to pre-heat the item before coating it. However, a friend, who works in a niche powdercoating company, said I should pre-heat. I thought that doing that would cause pre-flow of the PC, and might ruin the finish.
What do the experts (or at least, those with more experience than me 😀 ) say?
