Thank you to Squarehead and RobK for the tips on shooting flat black, aka 'murdered out', aka Darth Vader. I sprayed my first one for my oval car last weekend.
I'm going to paint everything like this for at least the next year. I may even shoot one in flat gray.
I used plain old Rustolium, and Rustolium tail light paint for the window tint. This is the before picture, but after a three day race it looks exactly the same. In fact, looks were the only saving grace because my truck was pig slow all weekend.
Thanks again.
