Polishing a car's paint involves a few key steps:

Wash and Dry: Start with a thorough wash to remove dirt and contaminants. Dry the car completely.
Clay Bar Treatment: Use a clay bar to remove embedded contaminants. This step helps create a smooth surface for polishing.
Inspect the Paint: Look for imperfections like swirl marks, scratches, or oxidation to determine which products to use.
Choose the Right Polish: Select a polishing compound based on the severity of the imperfections. For light scratches, a fine polish works well; for deeper scratches, a more abrasive compound may be necessary.
Tools: Use a dual-action polisher for the best results, but you can also polish by hand if preferred.
Apply the Polish:

If using a polisher, apply a small amount of polish to the pad and spread it over a section of the paint before turning on the machine.

Work in small sections, using overlapping passes in a circular or back-and-forth motion.

Buff Off: Once the polish has been worked into the paint, buff it off with a clean microfiber cloth.
Repeat as Needed: If there are still imperfections, you can repeat the process with a more aggressive polish or compound.
Finish Up: After polishing, apply a wax or sealant to protect the newly polished surface.
Final Inspection: Check the paint under different lighting to ensure all imperfections are addressed.
