1. Understanding the Causes of Bubbling Paint

What causes bubbling paint on a car? Bubbling paint, also known as paint blistering, occurs when the paint film loses adhesion to the underlying surface, forming bubbles or blisters. According to a study by the American Coatings Association, several factors contribute to this issue, including moisture, contamination, improper surface preparation, and incompatible paint systems.

• Moisture: Moisture trapped beneath the paint film is a primary cause. This can happen due to leaks, condensation, or inadequate drying time between coats. Research from the University of Michigan’s Automotive Engineering Department emphasizes that moisture levels above 5% can lead to significant adhesion problems.
• Contamination: Dirt, oil, wax, or other contaminants on the surface prevent proper paint adhesion. A study published in the Journal of Protective Coatings & Linings found that even microscopic levels of contamination can cause paint failure.
• Improper Surface Preparation: Inadequate sanding or failure to use a primer can result in poor adhesion. According to the Society of Automotive Engineers (SAE), proper surface preparation accounts for up to 70% of a successful paint job.
• Incompatible Paint Systems: Using different types of paint or clear coats that are not designed to work together can cause adhesion issues. A report by BASF Coatings GmbH highlights the importance of using compatible products from the same manufacturer to ensure chemical compatibility and proper bonding.
• Environmental Factors: Extreme temperature fluctuations and prolonged exposure to sunlight can also contribute to paint bubbling. Research by the National Renewable Energy Laboratory (NREL) indicates that UV radiation degrades paint polymers, leading to cracking and blistering over time.

Understanding these causes is the first step in effectively addressing and preventing bubbling paint on your vehicle, and is critical to getting a lasting repair with auto body filler.
