Why don't you paint the spray paint when the car is painted and the plastic primer is not sprayed?
Plastic paint spray must be sprayed with plastic primer! Without primer, it's easy to fall off! When the paint is removed, the paint is sprayed because the previous paint has a chemical reaction with the plastic parts, so that the adhesive force will not fall off...... It's really hard to organize language
The general is to use plastic or spray paint primer on tight over a period of time will fall second times for up to six months you played with sandpaper paint spray so it will not fall on but not played inside sandpaper should not long plastic primer can survive this summer.
