Why does car repair paint lack luster?
If there is a lack of gloss on the surface of the originally flat and smooth car paint surface, especially during the process of car paint care, it can be observed under a microscope that the surface is rough. What is the reason for this? Here is a brief analysis of the car repair paint, as follows:
1、 Poor adhesion of the primer, or topcoat sprayed on it before the primer has fully cured.
2、 The quality of the materials used for ensuring the operation of the paint is too poor or the type is incorrect, or other incompatible additives are used.
3、 Because the temperature is too high or too low, the monotonic speed of the coating is too slow.
4、 Improper paint distribution or spraying method.
5、 The surface quality of the substrate is too poor.
6、 Solvent vapor or car exhaust has penetrated the surface of the paint film.
7、 The surface of the paint film is contaminated with wax, grease, oil, soapy water, or water.
8、 Apply too aggressive detergents and cleaning agents before the newly sprayed paint film, and polish too early after spraying the topcoat, or use too thick polishing paste.
