CD Polisher & Extractor Equipment 2

Question 1

When using a dual-action (DA) polisher on a thin clear coat, what technique minimizes the risk of burn-through?

Accepted Answer

Keep the pad moving constantly and use low speed settings

Answer

Keeping the pad moving and using low speed prevents heat buildup that can burn through thin clear coats.

Question 2

What does the term 'throw' refer to on a dual-action polisher?

Accepted Answer

The distance the pad travels in its orbital path

Answer

Throw is the diameter of the eccentric orbital path the backing plate follows during operation.

Question 3

A hot water extractor used for interior detailing provides which key advantage over cold water extractors?

Accepted Answer

Better dissolution of oily soils and bacteria elimination

Answer

Hot water (150–200°F) breaks down oils and grease more effectively and sanitizes surfaces by killing bacteria.

Question 4

Which backing plate size is most commonly paired with a 5-inch polishing pad for detail work on body panels?

Accepted Answer

4-inch backing plate

Answer

A 4-inch backing plate is typically used with 5-inch pads, allowing the pad to extend slightly beyond the plate for edge contact.

Question 5

When priming a foam polishing pad before use, what is the correct procedure?

Accepted Answer

Apply a thin layer of product and work it into the pad before polishing

Answer

Priming the pad loads it with product so it doesn't absorb the first application unevenly, ensuring consistent results.
