Common automotive paint issues

Issue	Description
Bubbling	Small air bubbles form under the paint finish.

Understanding the issues

Bubbling

Bubbling can be caused by moisture trapped under the paint or incorrect mixing of paint components. It often appears as small blisters on the surface and can be unsightly.

Peeling

This is often the most frustrating paint issue for a car owner. Peeling can occur due to insufficient surface preparation or the use of low-quality paint. It's essential to ensure the surface is cleaned and primed adequately before applying paint.

Orange Peel

Orange Peel looks like the surface of an orange, and it can occur if the spray gun pressure is too low or if the paint is too thick. The result is an uneven finish that detracts from the visual appeal of the vehicle.

Use a heat gun to carefully remove bubbles after the paint has dried.
When mixing paint, ensure proper mixing ratios to avoid issues.

How to prevent peeling

Thoroughly clean and sand the surface to ensure proper adhesion.
Apply a high-quality primer before the paint.
Allow each coat of paint to dry fully before applying additional layers.
