Paint it, then wrap it. VHT and DEI make good aerosol "ceramic" header paint, lay on a few coats after you scotchbrite the pipes (especially the rust spots ) and remount them, and run them a while to cure the paint. Then clean them and wrap them with damp header wrap, go slow and it will turn out good. Let them dry a day, then shoot them with some of the wrap sealing paint that DEI and VHT make. I did 2 or 3 coats initially and have shot on another coat or touched up spots whenever the pipes were off the bike to get it on my lift and they look great.
header wrap paint and ceramic header paint are way different, but I cant give you specifics. I found both the wrap and wrap at my local Advance Auto Parts and both were DEI brand, though I here that VHT makes it for them.
