Question 1

____ are small, BB-sized dimples or craters that form in the liquid paint film right after spraying.

Accepted Answer

Paint-fish eyes are small, BB-sized dimples or craters that form in the liquid paint film right after spraying, often due to contamination on the surface being painted.

Question 2

Bull's-eye featheredge can be prevented by only using two-part spot putty and allowing proper time for putty or filler to cure.

Accepted Answer

Bull's-eye featheredge occurs when the putty or filler is not allowed to cure properly, causing it to shrink and create a visible line. Using two-part spot putty and allowing proper curing time prevents this from happening.

Question 3

____ appears as stretch marks, or cracking, along a featheredge.

Accepted Answer

Featheredge splitting specifically refers to the appearance of stretch marks or cracking along the featheredge of a painted surface, indicating a failure in the paint's ability to properly adhere and flex in this thin, tapered area.

Question 4

____, such as acid and alkali spotting, causes an obvious discoloration of the paint surface.

Accepted Answer

Chemical spotting, including acid and alkali spotting, directly leads to discoloration on the paint surface due to the chemical reaction between the spotting substance and the paint.

Question 5

Crazing is the beginning of film breakdown and might be an indication that film failures, such as cracking or crazing, will develop.

Accepted Answer

The answer of Crazing is the beginning of film breakdown...

Question 6

A ____ is a partial slipping down of the paint created by a film that is too heavy to support itself.

Accepted Answer

A paint sag occurs when a layer of paint is applied too thickly, causing it to droop or sag due to gravity before it has fully dried.

Question 7

____ is an uneven surface formation, much like that on the skin of an orange.

Accepted Answer

Orange peel is the term used to describe an uneven surface formation on painted surfaces that resembles the skin of an orange. This effect is often considered a flaw or imperfection in the paint application process.

Question 8

Line checking is similar to cracking, except that the lines or cracks are more parallel and range from very short to very long.

Accepted Answer

Line checking refers to a pattern of lines or cracks that are more parallel and can vary in length, distinguishing it from more random or web-like cracking patterns.

Question 9

Blushing results in fine splits or small cracks - often called "crow's-feet"- that completely checker an area in an irregular manner

Accepted Answer

Blushing refers to a whitish haze or cloudiness that appears on the surface of a finish, typically caused by moisture trapped in the finish or by rapid evaporation of the solvent. It does not cause physical splits or cracks in the surface.

Question 10

The term ____ refers to "blisters" or "pimples" on the paint surface caused by the paint topcoats trapping evaporating solvent gases during curing and drying.

Accepted Answer

Solvent popping is the correct term that refers to the appearance of blisters or pimples on the paint surface. This occurs when the paint topcoats trap evaporating solvent gases during the curing and drying process.

Question 11

____ occur when gravity produces a mass slippage of an overwet and thick paint film.

Accepted Answer

Paint runs occur when gravity causes an overly thick and wet paint film to slip or sag, leading to unevenness and drips in the paint surface.

Question 12

____ shows up as small, swelled areas on the finish that look like a water blister on human skin.

Accepted Answer

Blistering is the correct term for describing small, swelled areas on a finish that resemble water blisters on human skin. This defect occurs when bubbles form under the paint surface, often due to moisture or other contamination.

Question 13

Most clearcoats are designed to be applied after the basecoat fully cures.

Accepted Answer

Most clearcoats are designed to be applied over the basecoat while it is still tacky, not fully cured, to ensure proper adhesion and a seamless finish.

Question 14

Fish-eyes are commonly caused by improper body surface cleaning or preparation.

Accepted Answer

Fish-eyes are defects in a paint finish characterized by small, crater-like openings that can occur when the surface is not properly cleaned or prepared, leading to contamination that repels the paint.

Question 15

The most common causes of color difference include improper paint mixing and not spraying the paint on properly.

Accepted Answer

Improper paint mixing can lead to inconsistencies in color and finish, while incorrect application techniques, such as uneven spraying, can result in visible color differences on the surface being painted.

Question 16

Which of the following is LEAST-Likely the cause of crazing?

Accepted Answer

The answer of Which of the following is LEAST-Likely the...

Question 17

____ is the general dulling of gloss in spots or masses of spots.

Accepted Answer

Water spotting is the correct term for the general dulling of gloss in spots or masses of spots, typically caused by the deposition of minerals from water on the surface of a finish.

Question 18

The term primecoat show-through refers to a variation in the surface color.

Accepted Answer

Primecoat show-through refers to the phenomenon where the initial layer of paint (prime coat) affects the surface color, causing variations in hue or intensity visible through the final coat(s) of paint.

Question 19

Some product manufacturers rate their compounds or liquids and pastes by a grit rating system: #1000, #1500, #2000, and finer.

Accepted Answer

The grit rating system is used by manufacturers to indicate the coarseness or fineness of abrasive materials, including compounds, liquids, and pastes, with higher numbers representing finer abrasives.

Question 20

A buffing pad is used to clean and fluff up a wool buffing pad before machine compounding.

Accepted Answer

A buffing pad is used for polishing surfaces, not for cleaning or fluffing up another buffing pad.
