Is it okay not to repair bubbling car paint?

[McAlaina]

Bubbling car paint should not be ignored. Here are the details: 1. Impact: Bubbling affects aesthetics. If left untreated, the topcoat may crack over time, allowing rainwater to seep in, causing internal metal rust and expanding the damaged area, ultimately harming the car body. Therefore, once bubbling is noticed, it should be repaired by professionals at a specialized repair shop or 4S store. If the bubbling area is large, repainting may be necessary. 2. Cause: It might be due to internal rust under the paint, but the primary reason is often moisture trapped beneath the paint surface before it fully dries, followed by hasty painting. The topcoat layer has strong sealing properties, especially with two-component paints that fully react. If moisture is trapped within the paint film, it cannot easily evaporate. Under high temperatures, the underlying moisture expands, causing localized pressure on the topcoat film and resulting in bubbling.
