Common Automotive Paint Problems and How to Fix Them
Paint defects can result from contamination, poor preparation, incompatible products, incorrect application or unsuitable environmental conditions. Correct diagnosis is important before attempting a repair.
Peeling or Loss of Adhesion
Peeling can indicate poor adhesion, contamination, an incompatible substrate or coating failure. The damaged material may need to be removed and the surface properly prepared before refinishing.
Cracking
Cracking can be associated with excessive film build, incompatible layers, incorrect mixing or movement within the coating system. Follow the manufacturer's repair procedure rather than simply applying another coat over the defect.
Bubbling and Solvent Issues
Bubbles, pinholes or blistering can have several causes, including trapped air, moisture, contamination and incorrect application conditions. Identify the cause before sanding and repainting.
Fading or Dullness
Loss of gloss may result from UV exposure, oxidation, clear-coat deterioration, environmental conditions or application problems. Light oxidation may be polishable; severe coating failure generally requires refinishing.
Orange Peel
Orange peel is an uneven surface texture often influenced by gun setup, application technique, product viscosity and drying conditions. Follow the coating manufacturer's recommendations before changing pressure or thinning.
Chipping
Chipping can indicate impact damage or adhesion problems. Small chips may be repaired with suitable touch-up paint after preparation. Larger failures require more extensive repair.
