What is a common cause of paint failure during repairs?

Contamination of the surface, such as dust or oil, is a recognized common cause of paint failure during repairs. When a surface is not properly cleaned before the application of paint, contaminants can interfere with the adhesion of the paint to the substrate. This lack of adhesion can lead to several issues, including peeling, blistering, or improper curing of the paint.

For an effective paint application, the surface must be free from any substances that could compromise the bond between the paint and the material being painted. For example, oil can create a slick barrier, while dust can prevent the paint from adhering evenly. Therefore, ensuring a clean and contaminant-free surface is essential for achieving a durable and professional-looking finish in any paint repair job.
