How to Repair Bubbling Car Paint?

[StNoah]

It is necessary to sand the coating, remove all solvent bubbles, and repaint. Here is the relevant information: 1. Improper handling: There are many reasons for bubbling, such as rushing to paint before the body filler on the car has completely dried, or when doing bodywork, damaging the car's metal panel and not welding it in time before applying body filler, which can also cause bubbling. Additionally, if the primer applied before the topcoat is not cleaned properly or reacts, it can also cause bubbling. 2. Paint issues: For example, poor quality body filler, overly humid air during painting, incorrect paint mixing ratio, or not fully covering the area to be painted, leaving tiny edges exposed. There are many, many reasons, requiring the operator to gradually understand and experience during the work process to ultimately achieve perfect results.
