What are the main reasons for the lack of gloss on car paint, such as the full gloss before the paint film becomes dry, the lack of gloss after drying, or the gradual disappearance of paint film gloss in the future? The manufacturer of repair paint for Qingyuan Automobile provides us with a brief analysis as follows:

1. Poor adhesion of the primer, or spraying the topcoat on it before the primer has fully cured.

2. The quality of the thinner used in the paint is too poor or the model is incorrect, perhaps other incompatible or poor quality curing agents have been used.

3. Improper paint mixing or spraying methods, such as low viscosity or excessive atomization.

4. The surface quality of the substrate is too poor.

5. Due to high humidity or low temperature, the paint dries too slowly, and solvent vapor or car exhaust invades the surface of the paint film.

6. The surface of the paint film is contaminated by wax, oil, soapy water or water; Or the air in the grill is dirty, and the exhaust in the spray booth is poor, causing dry and solid spray particles to fall on the surface that has already been sprayed.

7. If too strong detergent or cleaning agent is used on the newly sprayed paint film, it may be polished too early after spraying, or the polishing wax used may be too coarse.

8. Spray the topcoat or varnish too thin.
