CAADE Repair and Refinishing Processes 3

Question 1

When estimating refinish labor time using a collision estimating guide, 'blend time' is used to account for:

Accepted Answer

Transitioning the new paint color into the adjacent panel for a seamless match

Answer

Blend time compensates for the labor of feathering and transitioning a new color coat into the existing finish on bordering panels.

Question 2

What is 'sand-scratch swelling' in automotive refinishing?

Accepted Answer

Solvent penetrating old paint causing underlying sanding marks to telegraph through the new finish

Answer

Solvents in fresh topcoats can swell and re-open old sanding scratches in the substrate, making them visible in the cured finish.

Question 3

In a structural repair, a sectioning joint on a unibody rail is best located:

Accepted Answer

In an area specified by the OEM repair procedure, away from stress-concentration zones

Answer

OEM procedures designate sectioning locations where the geometry, overlap, and welding specs ensure restored structural integrity.

Question 4

Which type of paint system requires the application of a separate clear coat to achieve gloss and protection?

Accepted Answer

Two-stage (basecoat/clearcoat) system

Answer

Two-stage systems use a pigmented basecoat for color and a separate clearcoat for gloss, UV protection, and durability.

Question 5

When a repair estimate includes 'overlap allowance,' this refers to:

Accepted Answer

A reduction in labor time when multiple adjacent panels are refinished together

Answer

Overlap allowance deducts labor time because a technician can refinish adjacent panels more efficiently in a single setup than individually.
