CAADE Repair and Refinishing Processes 2

Question 1

Which welding process is most commonly recommended for joining high-strength steel (HSS) panels in modern vehicle repair?

Accepted Answer

MIG (GMAW) welding

Answer

MIG welding is the industry standard for HSS repairs because it produces less heat distortion and maintains panel strength.

Question 2

When performing a blend repair on a metallic base coat, the blending solvent is applied to:

Accepted Answer

The adjacent panel edge after base coat application

Answer

Blending solvent is applied to the feathered edge of the adjacent panel after base coat to soften and melt in the new color.

Question 3

What is the primary purpose of a seam sealer in structural repairs?

Accepted Answer

To prevent corrosion and moisture intrusion at panel joints

Answer

Seam sealer prevents water, air, and contaminants from entering panel joints, protecting against rust and structural degradation.

Question 4

When estimating the cost of refinishing a door jamb during a full door replacement, the estimator should:

Accepted Answer

Always include jamb refinishing as a separate line item

Answer

Door jamb refinishing is typically a separate, billable operation because it requires masking and additional labor beyond the outer panel.

Question 5

Which surface preparation step is critical before applying a two-stage urethane primer-surfacer?

Accepted Answer

Scuffing or sanding to create mechanical adhesion

Answer

Scuffing or sanding creates a mechanical profile that allows the primer-surfacer to bond properly to the substrate.
