Watch out for
The things that quietly ruin the job.
- ·Light swirls don't need 3000. Going straight to compound is faster and removes less clear coat.
- ·Slow your polisher. Most swirls were created by polishing too hot or too aggressively the first time.
- ·Test on a small panel first. What looks like clear-coat damage may just be heavy oxidation.
