Question 4

When mixing and applying plastic filler, the minimum PPE the technician should use are safety glasses and cotton work gloves.

Question 5

The principal ingredients of the catalyst are butyl benzyl peroxide suspended in a variety of inert liquids and solvents.

Question 6

A gradual tapering of the filler to a very smooth edge. so it not possible to feel or see where the filler starts and the substrates begins. is called ____________________.

Question 7

The main body or the filler part of plastic filler consists essentially of a polyester resin, talc, and in some of the fillers, a combination of talc and microsphere.

Question 8

Technician A says that over-catalization of body filler causes pinholes. Technician B says that over-catalization of body filler can cause poor adhesion. Who is correct?

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

Question 9

When mixing plastic body filler with its hardener, the mixture should be stirred rapidly prior to application

Question 10

Technician A says structural foam is used to reinforce critical parts of the passenger compartment. Technician B says a two part glaze coat can be used as a final finish coat over all other fillers. Who is correct?

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

Question 11

____________________ is the principal ingredient in the catalyst or hardener responsible for creating the chemical reaction which causes the plastic to harden.

Question 12

Technician A says visible streaks of catalyst or hardener left in the plastic indicates it hasn't cured properly and should not be sanded yet. Technician B says grating the plastic filler should not be done until the filler has fully hardened. Who is correct?

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

Question 13

Technician A says a temperature sensitive can be catalyzed with standard catalyst. Technician B says the surface used to mix plastic filler will have little affect on its adhesion ability. clean cardboard can be used for a plastic mixing surface Who is correct?

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

Question 14

Technician A says that for many years the auto manufacturers have used foams and other fillers for preventing water leaks, eliminating wind noises, filling seams where panels overlap, and filling unsightly gaps. Technician B says that aluminum clad body fillers are not waterproof. Who is correct?

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

Question 15

One must be careful to not start grating the filler prematurely,as it will pull the material off the substrate because it isn't properly anchored to the surface until it is thoroughly cured.

Question 16

Technician A says that a dam can be made on a vertical surface with foam by slowly applying it and allowing it to form as it is applied slowly. Technician B says a balloon or tape can be used to make a dam for the foam inside a cavity. Who is correct?

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

Question 17

____________________ resin is fiberglass resin designed to be used on vertical surfaces to reduce the possibility of the repair materials sagging before they cure.

Question 18

A subtle texture in the topcoat outlining the area where plastic filler has been applied which appears after the primers, topcoat and clearcoat have been applied. It is usually caused by solvent penetration into the feathered edge of the plastic causing it to slightly lift off the surface is called ____________________.

Question 19

Technician A says that after all the surface coatings have been removed down to the bare substrate, it is advisable to solvent wipe the surface. Technician B says that the two most popular types of applicators are a urethane plastic type and a steel putty knife. Who is correct?

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

Question 20

Technician A says plastic fillers can readily be applied over a rust perforated surface so long as it has been sanded smooth and free of paint. Technician B says the premium grade fillers are less apt to stain because they use a clear liquid hardener. Who is correct?

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

Question 21

What may happen if separated resin at the top of plastic body filler is removed?

Question 22

Why is cardboard not a good material on which to mix plastic body filler?

Question 23

Describe how plastic body filler could have adhesion loss.

Question 24

Explain what may happen if grating of plastic body filler is started too early.

Question 25

Describe what polyester resin is used for in collision repair.
