What is the reason for the lack of a mirror-like effect after car painting?

[CaliRose]

Possible reasons include poor adhesion of the primer or the topcoat being applied before the primer was fully cured. Here is some relevant information: 1. Introduction to Polishing: Car polishing is a step in the car detailing process, performed before waxing, sealing, or coating to achieve a mirror-like finish. Polishing, especially fine polishing, is essential for creating a reflective surface, which is a necessary step before applying sealants or coatings. 2. Prospects: Currently, the demand for car polishing is high, while the supply is somewhat insufficient. There are particularly few companies with core intellectual property rights and high-quality products, and the industry as a whole lacks brand recognition. During this period of strong demand, the industry has significant potential and promising development prospects.
