During the process of repairing car paint, there is sometimes a phenomenon where the paint film is dull and shiny, but after monotony, the gloss may gradually fade. What is the common cause of this phenomenon? A brief analysis of the reasons for the Guangzhou automotive paint coating manufacturer and everyone is as follows:

1. The adhesion of the primer is poor, and perhaps the topcoat is sprayed on it before the primer has fully cured;

2. The paint mixing ratio is not correct, for example, the curing agent is not good, perhaps there are too many diluents;

3. The diluent used in the paint may have poor quality curing agents, or may have used incompatible products;
