I know that a lot of CEG'ers got screwed by PowderCoatMan - I at least received my parts from him, though I was not at all happy with the quality of work.
I have found a powdercoating place in Northern Virginia that does excellent work. They are a little on the pricey side when it comes to things that have to be masked (UIM, valve covers, etc) but honestly, the quality is flawless.
The name of the company is American Stripping. They have several offices nationwide. They clean the item before coating it and know how to handle all sorts of body parts.
Just thought I'd offer this up as an FYI. If you don't have access to an American Stripping place, I am willing to be the go between. Their turnaround time is generally a week, no more than a week and a half. I got a rear strut bar coated for $55 and my valve covers coated again (thanks to Powdercoatman) for $190.
I post all the time over on newcougar.org, but again, thought I'd share the info with the peeps here!
