Valspar Clear Flat Finish vs. Dullcoat

[nachoman]

One day, needing to do a small touch-up, he used a spray can of the same paint, only to discover that the spray cans used a lacquer-based thinner, which promptly removed or damaged the previously applied paint upon which it landed.

Good point, Wayne. Some paints even react with themselves. Rustoleum enamels can be recoated within about an hour, or after a about two days. I learned the hard way what happens if you try to spray a second coat a few hours after the first one. The second coat will actually react with the partially dry first coat and cause the paint to blister and craze.

I have always been a strong advocate of petroleum based paints for airbushing. But more and more I am considering acrylic alternatives and have been having more recent success with acrylic. Perhaps the acrylic paints have gotten better, or it has to do with my technique. I have been wondering about the possibility of spraying acrylic matte medium as a dullcote alternative. Has anyone tried this?
