When detailing a car, the general consensus is that you should polish after using a clay bar. Here’s a breakdown of why this order is recommended:

1. Purpose of Clay Bar: The clay bar is used to remove contaminants from the paint surface, such as dirt, tar, and old wax. This process leaves the paint smooth but can sometimes cause minor marring or imperfections.

2. Polishing After Claying: Polishing is recommended after claying because it helps to remove any marring that may have occurred during the clay process. It also prepares the paint surface for the application of wax or sealant, ensuring a better bond and a glossier finish.

3. Not Always Necessary: While polishing after claying is beneficial, it is not strictly necessary in all cases. If the paint is in good condition and you are only removing light contaminants, you might skip polishing and go straight to applying a protective layer [1].

Summary

• Clay Bar: Use first to clean the paint.
• Polish: Use after claying to enhance the finish and prepare for protection.
