What are the main reasons for the lack of gloss on car paint surfaces, such as full gloss before drying, lack of gloss after drying, or gradual disappearance of gloss in the future? Here is a brief analysis of automotive repair paint suppliers with us:

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 preparation 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 drying speed is too slow, 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. Too strong detergent or cleaner was used on the newly sprayed paint film, perhaps polishing was done too early after spraying, or the polishing wax used was too coarse.

8. Spray the topcoat or varnish too thin.
