A) Spray gun triggering
B) Spray overlap
C) Spray gun direction
D) Atomization

Answer 2

C

Question 3

Improper viscosity can cause excessive overspray, increased booth maintenance, runs or sags, pebble-dry finishes, and color mismatches.

Answer 3

True

Question 4

Wasteful overspray is caused by a failure to trigger a spray gun before and after each stroke.

Question 5

Spray gun feed refers to how the liquid material is fed into the gun body.

Question 6

A ____ checks the operation of the spray gun on a piece of paper.

A) pattern test
B) fluid test
C) viscosity test
D) spray pattern test

Question 7

____ breaks the liquid material into a fine mist spray of tiny, uniform droplets.

A) Crossflow
B) Atomization
C) Arcing
D) Heeling

Question 8

High-volume efficiency means that more of the material leaving the gun stays on the surface being refinished.

Question 9

You set the size of the spray pattern using the ____.

A) air valve
B) pattern control knob
C) fluid control knob
D) stroke

Question 10

Low spray gun pressure results in excessive paint loss through overspray and poor flow due to high solvent evaporation before the paint reaches the surface.

Question 11

A spray gun breaks the liquid sealer, primer, paint, and so on into a fine mist and forces it onto the surfaces of the vehicle.

Question 12

____ use airflow through the gun head to form a siphoning action (negative pressure) in the cup that pulls the refinish liquid through the gun body and into the airstream.

A) Suction spray guns
B) Gravity-fed spray guns
C) Pressure-fed spray guns
D) Fluid control knobs

Question 13

Viscosity of sprayable materials is measured in minutes.

Question 14

A gravity-fed gun is more likely to leak and drip paint when spraying.

Question 15

If spray gun distance is too close, the high velocity of the spraying air tends to ripple the wet paint film.

Question 16

____ ensures full, even coverage without applying too much paint at once.

A) Spray stroke
B) Spray overlap
C) Viscosity
D) High-transfer efficiency

Question 17

____ involves keeping constant airflow out of the nozzle and only triggering paint flow when depositing paint materials on the body.

A) Spray gun triggering
B) Atomization
C) Heeling
D) Arcing

Question 18

A spray gun normally has two adjustment knobs: fluid adjustment and pattern adjustment.

Question 19

All of the following represent the basic equipment needed to operate a spray gun EXCEPT:

A) an air hose
B) a sensor
C) an air compressor
D) a filter

Question 20

Which of the following variables LEAST-Likely contributes to the quality of a spray finish?

A) An agitation paddle
B) Cleanliness
C) Compressed air
D) Light

Question 21

____________________ is the measurement of thickness, fluidity, or flow resistance of a liquid.

Question 22

The tool that is used to suspend or secure individual components or small parts for spray painting is MOST-Likely the:

A) paint hanger
B) spray booth
C) strainer
D) paint shaker

Question 23

The _________ sucks paint from the cup, up the fluid inlet, and out through the open fluid tip.

Question 24

_________________________ is how fast you move the gun sideways over the surface.

Question 25

The ____ of more sophisticated paint shops have permanent infrared or sodium quartz units for the forced drying of paint, particularly enamels.

A) suction spray guns
B) drying rooms
C) spray gun cleaning tank
D) suspension systems

Question 26

Which of the following is LEAST-Likely a type of spray gun?

A) Airless spray gun
B) Electrostatic
C) Airbrush
D) Trigger

Question 27

While having a discussion, Technician A says that cotton clothing is perhaps the greatest source of contamination and should never be worn in a spray booth.Technician B says that lint-free paint suits, rubber form-fitting gloves, a dirt-free head cover, and the appropriate respirator should be worn inside the booth.Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 28

____ is compatible with paint and will not contaminate the gun.

A) Jounce
B) Camber
C) Spray gun oil
D) Caster

Question 29

How do you keep dirt from becoming a problem in a finish during body repairs?

Question 30

What is the difference between masking paper and masking tape?

Question 31

_________________________ refers to the hand motion used to move the gun while spraying.

Question 32

____ is a gun handling problem that occurs when the spray gun is not moved parallel with the surface.

A) Arcing
B) Atomization
C) Heeling
D) Overspray

Question 33

What information should you bear in mind when evaluating a spray pattern test?

Question 34

A ____ indicates how much airflow is going through a paint booth.

A) booth manometer
B) thermostat
C) drive shaft
D) transaxle

Question 35

The tool that is used to weigh paint ingredients when mixing the paint to match the original color or tone is MOST-Likely the:

A) strainer
B) spray booth
C) paint shaker
D) paint scale

Question 36

When using a spray gun, how do you avoid air supply and painting problems?

Question 37

While having a discussion about air spray guns, Technician A says that one possible cause of the spray pattern being top or bottom heavy is that the horn holes could be partially plugged.Technician B says that one possible cause could be that the atomizing pressure is too low.Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 38

____ occurs when the painter allows the gun to tilt.
