How to Solve Paint Bubbling?

Use a needle to puncture the bubble to determine its depth. Then, use a low-power magnifying glass to inspect the cause of the bubble. When the bubble occurs between paint layers, sand down the defective area to expose the intact paint layer before repainting. For small damaged areas, use soapy water to sand until smooth, then seal with a two-component primer. After drying, repaint using a two-step color paint process.

I've dealt with paint bubbling before, and I feel the key is to take it step by step. Bubbling is usually caused by surface contamination or excessive moisture. I remember when I was painting a car door, bubbles appeared, likely due to residual wax not being completely removed after washing. Solution: First, gently sand the bubbled area with fine sandpaper to smooth and polish it, being careful not to apply too much pressure to avoid damaging the primer. Then, thoroughly wipe off grease and dust with alcohol or a dedicated degreaser to ensure the surface is dry. Environmental control is crucial—choose dry weather with low humidity for painting, avoiding post-rain dampness. Apply the paint in thin, multiple layers, allowing each layer to dry for 10 minutes before applying the next, rather than rushing with a thick coat at once. For prevention, park the car in a ventilated area for half an hour before painting to remove moisture, and ensure the surface is thoroughly cleaned to save trouble later. In short, patience and proper preparation are key.

In the car detailing industry, paint bubbling is a common issue often caused by surface contamination or environmental moisture. The treatment steps are as follows: first, sand the bubbled area until smooth, remove oil stains with a cleaner, and then apply a layer of primer as a foundation. Use high-quality paint for the color coat, applying thin layers multiple times with sufficient intervals to allow solvent evaporation. For prevention, ensure the car body is dry and dust-free before painting, and control humidity below 60%; check the freshness of the paint, as expired products are prone to issues. For daily maintenance, avoid using wax-based products on painted areas. If there are too many bubbles or the affected area is large, it is recommended to seek professional shop services for a more hassle-free solution.

Bubbles are really annoying. Last time I sprayed the tail light cover myself and bubbles appeared, so I looked up solutions. The cause was oil or moisture mixing in. Simple fix: sand the bubble spots flat with sandpaper, clean the surface with detergent to remove grease; spray paint in thin layers, waiting for each layer to dry before continuing. Keep the environment from being too humid, open windows for ventilation indoors. For prevention, ensure the surface is dust-free and dry before spraying, and don't store paint after opening. This way, small issues can be handled with DIY.
