Which of the following are signs of paint incompatibility?

Adhesion failure, blistering, and wrinkling
High gloss finish and quick drying time
Even color coverage and smooth texture
Color fading and oxidation

The correct answer is: Adhesion failure, blistering, and wrinkling

Adhesion failure, blistering, and wrinkling are indeed signs of paint incompatibility. When two different types of paint or coatings are applied on a surface without proper compatibility, issues arise that affect the integrity and appearance of the finish. Adhesion failure occurs when the new layer of paint does not properly bond with the underlying layer, which can lead to peeling or flaking. Blistering is a result of trapped solvent or moisture beneath the paint film, which can create bubbles or blisters on the surface. Wrinkling often happens when a topcoat reacts adversely with the underlying layer, resulting in a textured finish that is far from ideal. These signs are crucial indicators that suggest the materials used are not meant to work together, which can significantly compromise the overall quality and durability of the automotive finish. Identifying these problems early on can help prevent costly rework and ensure that the final paint job meets the expected standards.
