1964 Valiant "Get Runnin & Drivin"
I can chime in on the Rustoleum paints. I shot my kmember, rear end and various suspension pieces with their gloss black. I thinned with acetone, per the instructions on the CAN.
They turned out incredible, although I can speak to durability, because the car isn't finished yet, but parts still look great.
A few before and afters.
