hmm for the frame u could probably do an undercoating type of thing.. im not sure if HOK has a hi-temp paint...
Sorry dude i was just assuming you were using cans, im so used to everyone doing cans...lol there seem to be less of us doing the ole' compressor and gun thing here lately..lol
I was researching paint matching my 350 when I was planning on painting my Ford a burgundy color. There is actually something that you mix into the base. And there is something you spray before you spray the base. I don't remember what anythign is called, because that was almost 4 years ago. So you can paint it any color you want. The stuff to do it is expensive though.
you can also do a high temp sealer, that way no heat will ever make it out of the sealer to harm your paint. look into to the HOK hi heat sealer/primer.i sued it on mine and no cracking, bubbling, any discoloration, nothing. good luck.
