The way I painted mine was do the sanding bit, then hit it with a couple coats of rattle can primer (rustoleum automotive I think), then a few coats of "semi flat" high temp paint, also rattle can, and of course sanding between coats as appropriate. Since then, I've heard that baking just about any rattle can paint can actually help it adhere better because it makes the solvents go away faster. That being said, I painted the lower tripple tree, fork legs, headlight bucket, tank console, and a few other things that same way, not a scratch on it 10,000 mi later...
