Where are you located? From your other post in the racing forum, I would assume that you are in Cali. There are quite a few places that do coatings for exhaust manifolds and other engine parts in Los Angeles. Swain Technology has a shop in southern California, but I can't find what I did with the address. I will post it up when I find it.
