Learning to paint....

But the guy on the U tube said rustoleum was da bomb!

LOL!!! I know you are jolking! But not everyone knows the guy on UTube is also a duffous!!!! LOL
I love it for floor pans, bottoms of drivers and yes it is very tough and durable! But it is not intended to be a topcoat for autos!!!!! There is a reason Rustoleum is $30 a gal and decent single stage acryllic urethane or enamel is $265 plus hardner and reducer.
