I can't imagine a roll on top final coat of paint - especially Rust-O-leum. It's hard enough to get consistant film coverage with a decent spray gun, a roller would be impossible. Just think of painting a wall in your house. When you load the roller from the pan, the paint on the first stroke is fairly heavy with each suceeding pass it is thinner. A tooth brush is too stiff, but I have some $.69 chip brushes that are perfect.

I do recall my father painting his '41 Chevy using some pads similar to my wife's powder puffs. I was too young to remember the quality, but do recall my parents not being overjoyed with the results and talking about it years later after a new car.

Hot Rod Magazine has had, IMO, credibility problems for many years and something like this sure doesn't strengthen my opinion. If I can 'read' it once in the barber shop, that's my diet for the year of their trendy ricer language.
