What Causes Small Bubbles in Paint?

[Stacy]

The reason for small bubbles in paint: During the car painting process, a large number of water molecules enter the middle layer of the car paint film through certain channels. If not thoroughly dried and removed during baking, these water molecules remain latent and gradually gather into small water clusters under suitable conditions. They then move between the dried intermediate paint film and the topcoat, forming paint film bubbles. Glaze Sealing: In addition to the benefits provided by wax, glaze sealing can enhance the strength of the car paint and prevent fine scratches caused by windblown sand hitting the car body. The effects last relatively longer, typically around 3 to 4 months. Waxing: Waxing is the most traditional and economical method for protecting car paint. Its primary functions include inhibiting oxidation from external harmful elements, providing UV resistance, and to some extent, enhancing the brightness of the car paint. Coating: Paint coating treatments are generally more expensive. They form a transparent protective film on the car body, offering better protection than waxing or glaze sealing. The effects typically last about a year.
