Paint Blistering (Rust Bubbles)
Paint blistering is raised bubbles in the paint, often caused by rust forming underneath.
What is Paint Blistering (Rust Bubbles)?
It is common at wheel arches, sills, door bottoms and around trims. Moisture or contamination under fresh paint can also cause blisters. Blisters hide damage that is usually larger than it looks. Blisters on fresh paint point to contamination or moisture during the respray.
How it works
Rust or trapped moisture expands under the paint and lifts it from the metal.
Why it matters for your car
Repair early, before rust spreads or perforates the panel. Grinding back to clean metal is usually needed.
