I have done many spray paints. I used this specific primer as a base coat on a plastic part before the final paint with color. It is a clear primer, I applied a light layer to cover at the recommended distance (25-30cm). After it dried, I applied paint from the same company for the final result. 1 hour later it had not dried to a strong touch. 2-3 hours later, with a nail touch, it left a mark. Supposedly, the primer was applied for extra adhesion and in the end, the result was terrible. I had to get nitro thinner to strip the bad paint and the substrate (primer). On the negative side, the primer also has an unpleasant smell, 24 hours of ventilation in the space and it still smells unpleasant, not like paint, much worse. The product was disappointing, wasted money

Apart from the fact that I have painted all the plastic parts (after lightly sanding them as necessary), I applied 2 coats (1 coat to dry and then another coat to dry) and then used the paint gun to apply the color, and they looked like new (the longer you let them dry, the better the result). Do not leave them in the sun to dry quickly because you will not get good results, especially in hot weather. I also tried it on a cover (vehicle plastic) and painted it, the result was excellent and I did not expect it, you just need to apply 3 coats with primer and let it dry somewhere where it won't be exposed to the sun for a while after painting.
