He's using Ace Rust Stop (a Sherwin Williams Paint), it's international blue, and the name of his website makes a dirty old man wanna reach for the viagra!

Good job on the tailgate. I'm still hand sanding down my satellite (the guy I bought the car hand painted it with a brush three years ago,and it's filled with orange peel, brush strokes, and runs) and I'm getting ready to rust bullet the underside of my bulge hood.

It's nice to see another Ace Rust Stop guy on the thread...talk about inexpensive paint!
