My feeling was that different colours are different. I used three, one that erupted into a massive cloud of powdery dust and was very difficult to get to cover (fluoro orange), one that went on fine and came out fairly smooth (quasar), one that tended to go on wet and then would get rough (dark green).
I also did quite a lot of careful priming and stuff, and I didn't get the feeling that you can just whack it on over anything and expect it to stick.
I used that, it was actually pretty good.
The colour coats go on like powder which doesn't stick. You can rub it off as it stays all dry powdery. My experience was this anyway
