John, I used it on my '38. I rolled the body and sprayed the fenders.
I diluted it 50% with acetone so it went on very thin. I wet sanded after each coat with 24 dry time using 400 grit paper. It took 4 coats minimum, some areas took 5.
After 5 years being parked under a carport, it's starting to lose it's shine. I purposely haven't polished or waxed it because i want it to get an aged look.
Take a look at my photos below.
