I need help. I suck at spray paint work. It seems to crack on me. Am I doing it too close? Not waiting long enough? To much paint?
More than likely the WRONG kind of the paint for the plastic.
What you have there is called
crazing, a modelmaking term for paint incompatibility with plastic.
Lemme guess, you used a enamel paint from a can, something like Testors?
The key here, with these kinds of plastics, is to use an acrylic primer as a base coat--then you can spray on just about anything over top. Acrylics will not craze on plastic--if applied right ( meaning don't use too much thinning chemicals--stick with water).
