5. How do you prevent or correct sanding mistakes?

• Burn marks: Caused by excessive friction. Prevent by using a lower grit and applying less pressure.
• Gouges: Caused by applying too much pressure or using a coarse grit. Correct by sanding with a finer grit and using a lighter touch.
• Uneven sanding: Caused by inconsistent sanding pressure or technique. Correct by re-sanding with a uniform motion and applying even pressure.
