Why is My Car Paint Cracking?
Several factors contribute to cracked car paint. UV rays from the sun can degrade the paint’s elasticity over time. Improper paint preparation, such as inadequate cleaning or priming, can also lead to cracking. Impacts from rocks or other debris can cause small cracks that spread if left untreated. Finally, applying a new coat of paint over an incompatible existing layer can cause the new paint to crack.
Identifying the Type of Crack
Knowing the type of crack you’re dealing with is essential for choosing the right repair method. Hairline cracks are thin and superficial, often caused by UV damage. Deeper cracks, exposing the primer or metal, require more extensive repair. “Alligatoring” describes a network of interconnected cracks, usually indicating a serious paint failure.
