What Causes Paint Bubbling on the Hood?

[MadelynDella]

The reasons for paint bubbling on the hood are as follows: Putty not fully dried: First, it is caused by rushing to paint before the putty applied to the car has completely dried. Damaged metal sheet not welded in time: During bodywork, if the car's metal sheet is damaged and not welded in time before applying putty, it can also cause bubbling. Primer not properly treated: If the primer applied before the topcoat is not properly treated or reacts with other materials, it can lead to bubbling. Incorrect paint mixing ratio: There are many other reasons that can cause bubbling, such as poor-quality putty, overly humid air during painting, incorrect paint mixing ratio, or not fully covering the area to be painted, leaving minor edges exposed.
