Question 1

When using a dual-action (DA) polisher on a soft paint system, which pad type minimizes the risk of burning through?

Accepted Answer

Foam finishing pad

Answer

A foam finishing pad on a DA polisher generates less heat and aggression, making it safer on soft or thin paint systems.

Question 2

What is the primary purpose of a 'finishing polish' in a multi-stage paint correction process?

Accepted Answer

Refine the surface and remove light haze left by cutting compounds

Answer

A finishing polish is designed to remove micro-marring and haze left by more aggressive compounds or polishes, leaving a refined, high-gloss surface.

Question 3

Which machine polisher type produces a true random orbital motion, making it the safest choice for beginners?

Accepted Answer

Free-spinning dual-action (DA) polisher

Answer

A free-spinning DA polisher stops rotating when excessive pressure is applied, greatly reducing the risk of heat buildup and paint damage.

Question 4

A detailer notices swirl marks remaining after using a medium-cut compound with a foam pad. The BEST next step is to:

Accepted Answer

Step up to a more aggressive compound and cutting pad combination

Answer

If the current combination is insufficient to remove defects, increasing cutting power through a more aggressive compound and pad pairing is the correct approach.

Question 5

What does 'diminishing abrasive technology' (DAT) mean in modern polishing compounds?

Accepted Answer

Abrasive particles break down into finer particles as they work, transitioning from cut to finish

Answer

DAT compounds start with larger abrasive particles that fracture and diminish in size during polishing, allowing a single product to cut and then finish.
