Paint not setting up.

I'm not using a "base coat system," it is a single stage top coat. No clear coat involved. Am I missing something here? I wanted the dash board to be durable...didn't want to do a "rattle can" job or shoot some straight acrylic and I didn't want to screw around with clear coat on a dash board. Relating that to the dealer, they said this was just the thing I needed. Ultra 7000 single stage top coat. It was the first time I stopped at the Sherwin Williams dealer. We have been spraying DuPont Emron and NASON Ful-Thane single stage we get from Crowe Burlingame and have never had a problem with it at our shop.

Basecoat does not always have to be topcoated. Especially in an interior application if using hardeners. Did you click the link? You were led astray in the products needed for the application. You omitted the base coat stabilizer
