Yea I was thinking the same. Perhaps even start with a coat or two with the matte black and then with glossy black, finish it off with the glossifier for the added UV protection and more gloss? Or is that overkill??
I read the directions on the glossy black. You have to spray wet even coats. So you don't do light coats like with the matte and build up to heavy wet coats. Since it already has gloss in it, it must be applied wet. I think that might be the problem.
