What is the basic starting requirement for any effective repair process?

Explanation:
Starting with a clean surface is essential because any dirt, oil, grease, wax, or moisture can prevent adhesives, fillers, primers, and paints from bonding properly. When the surface is clean, you remove these contaminants so the next repair steps—whether bonding, priming, or coating—can achieve good adhesion and a durable, uniform finish. Even if a surface is rough or smooth, or has been primed, those conditions won’t lead to a reliable repair if contaminants remain. Cleaning lays the foundation for all subsequent preparation and application steps.
