Moisture Trapped Under the Paint
Moisture is a frequent culprit in paint blistering. This can occur when water seeps in through a chip or crack in the paint, or even through improper car washing techniques.
Exposure to Harsh Chemicals
Certain chemicals, like bird droppings or acidic cleaning solutions, can react with the paint and cause it to blister.
Poor Paint Application

Impact Damage
Rocks, debris, or even minor collisions can damage the paint layer, allowing moisture to penetrate and cause blisters.
Gathering the Necessary Materials
Once you’ve identified the cause, gather the following materials: sandpaper (various grits), primer, automotive paint (matching your car’s color), clear coat, masking tape, plastic sheeting, rubbing compound, polishing compound, and a few clean microfiber cloths. Having the right tools will make the repair process smoother and more efficient.
Preparing the Affected Area
Thoroughly clean the blistered area with soap and water. Dry the area completely. Using the appropriate grit sandpaper, carefully sand down the blistered paint until you reach a smooth, even surface.

Protecting the Surrounding Area
Use masking tape and plastic sheeting to protect the surrounding areas of the car from paint overspray.
Applying Primer and Paint

Once dry, apply several thin coats of automotive paint, allowing each coat to dry before applying the next. How to repair mini paint blisters by car cover can involve similar steps.
