Swirl marks are fine circular scratches caused by dragging dirt across paint during improper washing or drying with contaminated mitts and towels.

Question 3

What does the term 'buffer trails' refer to in paint correction?

Accepted Answer

Holograms or marring left by a rotary polisher

Buffer trails (holograms) are fine swirling marks left in paint when a rotary buffer is used at too high a speed or with too much pressure.

Question 4

Which type of paint defect cannot be corrected through polishing and requires wet sanding?

Accepted Answer

Deep scratches that penetrate through the clear coat

Deep scratches that reach the base coat or primer cannot be leveled by polishing alone and require wet sanding to reduce the scratch before polishing.

Question 5

What is the purpose of a paint inspection light or LED swirl finder when performing paint correction?

To reveal surface defects, swirls, and scratches that are invisible in normal lighting

Answer

A focused inspection light or swirl finder illuminates the paint at a specific angle, making fine swirls, marring, and scratches clearly visible before and after correction.
