I've used it quite a bit and have no problems.
Spray over a black base for maximum color and flop. They say a value shade of 6, which is just a dark grey. Go with black.
It doesn't matter in which direction you spray it will all come out the same, so color match and touch ups are easy.
I was told to use a catalyst that they have from a bus. that paints graphics on the side of trucks. They had a golf ball size bubble form after the truck was painted and couldn't figure it out. DuPont said the paint dries too fast and hard between coats, so it had poor adhesion. Well, not being able to justify spending $50 for the catalyst, just to use a few drops per use, I skipped it and sprayed it anyway. Needless to say after about three years later I've experienced zero problems with it.
The only thing I don't like about it is the UGLY
UPS brown that you get in some angles.
Other than that, it's a fine paint.
