Hey guys, I’ve only PC’d steel so far. I have a set of Mopar Performance valve covers for my truck and I wanted to get them PC’d Candy blue.
So what I wanted to know was, what kind of prep do I need to do to the Alum. I didnt want to use anything that would hurt the alum or cause problems with the coating. Should I just glass bead them at 60psi, pre cook them, and then coat them?
