Your headers look a bit bronze, I assume thats the color you sprayed? And, one can is the coverage for a set of headers. One coat is all that's needed? Is there a certain temp it needs to cure at?
Correct, that is the color I went with. The cans come in few different sizes. I went with the 8oz can. They say that’s enough to do a set of long tube headers and that seems to be accurate from my experience. I sprayed it at 40psi (they recommend 30psi) and that probably worked to my benefit because it comes out a little thinner. I called them a few times with questions prior to doing this because I didn’t want to screw it up. I didn’t know if it would run or what. I’m his words (Tim is the man I talked to), a left right left right spray and you’re done. He said basically when the header changes color, that’s about enough to do the job. For curing, he said 5 days of air drying or 2 hours at 450° cures them. He did warn that with air drying, one should let the engine idle and get up to temperature as slow as possible to lessen chances of a flare-up in the spray. He said the baking method pretty much eliminates that worry.
