What is the first step in repairing nicks in a body panel?

The first step in repairing nicks in a body panel involves dewaxing. This process is essential because it ensures that any wax, grease, or contaminants present on the surface of the panel are removed. These substances can hinder the adhesion of subsequent materials, such as fillers or primers, which are critical for achieving a smooth and lasting repair. Dewaxing helps to prepare the surface by promoting better adhesion and ultimately leads to a more effective and durable repair outcome.

In the context of the repair process, after dewaxing, sanding would follow to smooth the area and create a texture that helps the filler adhere properly. However, without first dewaxing the surface, the repair materials may not bond effectively, which could lead to premature failure of the repair.
