Powder coating shop...
 

I have seen a couple people ask where to get powder coating done. This is where I have all my stuff done for my brake kits. They are good guys, and do top rate work, but turn around is normally two weeks after they say it will be ready.

They even have high temp stuff for your headers, or even your heads, and cylinders good up to 2000 degs F.
