When detailing a car, the correct order of operations is crucial for achieving the best results. In this case, you should use the clay bar first, followed by polish.

Why Use a Clay Bar First?

The clay bar is designed to remove contaminants that are bonded to the surface of the paint, such as dirt, tar, and industrial fallout. This step is essential because it prepares the surface for polishing. If you polish before claying, you risk grinding these contaminants into the paint, which can cause scratches and marring.

After Claying, Use Polish

Once the surface is clean from contaminants, you can proceed to polish. Polishing helps to refine the paint surface, removing any light scratches or imperfections that may have been introduced during the claying process. It enhances the gloss and clarity of the paint, making it look more vibrant.

Summary

1. Clay Bar: Removes surface contaminants.
2. Polish: Refines the paint surface and enhances gloss.
