Powdercoat prep?

thanks guys. I talked to the powder coater yesterday. They will cleanup any surface rust and use some kind of etching compound before coating. We also discussed a high temp coating for headers, anybody done this? Does it hold up?

Wow, didn't think I could share some information on here already, lol

But anyways, I do some powder coating on the side as a small business. The etching compound is more then likely a iron phosphate solution which helps the powder bond and also prevents flash rusting. The high temp coating will hold, but I would have them ceramic coated which will help reduce under hood temps and help the exhaust flow.
