I have been trying it out. I shot some wood and plastic (plexiglass) with a white spraybomb primer. The primer laid down really nice. I shot some of the AutoAir transparent colors over the top of it without sanding it (trying to see how forgiving the paint could be) and it orange peeled real bad. The acrylic did actually fill in while it dried, minimizing the peel. But this was on a flat horizontal surface, paint facing up...I think if the stuff has more time it sag it would. I am going to try light sanding to see if the previous is worst case scenario. They say on the website to use many thin coats. I believe them. I think this stuff will be pretty trick once you figure out the learning curve. The colors are unlimited. The paints are inexpensive so you can mix shades and hues till you get tired for minimal costs. And I can shoot it in the house during these sub zero winter days....
