What Causes Car Paint to Bubble?

Car paint bubbling can stem from various factors, often indicating an underlying issue that requires attention. Here are some common culprits:

1. Moisture:

One of the most frequent causes is moisture seeping beneath the paint layers. This can occur due to improper car washes, parking in damp areas for extended periods, or driving through floodwaters.

2. UV Radiation:

Prolonged exposure to the sun’s harmful ultraviolet (UV) rays can degrade the paint’s chemical composition, leading to bubbling and peeling.

3. Improper Paint Application:

A rushed or poorly executed paint job can result in inadequate adhesion between the paint layers, creating vulnerabilities for air and moisture to become trapped.

4. Chemical Exposure:

Contact with harsh chemicals, such as bird droppings, tree sap, or industrial fallout, can damage the paint’s protective layer and contribute to bubbling.

5. Underlying Rust:

Rust formation beneath the paint is a serious concern. As rust expands, it pushes the paint upward, causing bubbles to appear on the surface.
