CAADE Repair and Refinishing Processes 5

Question 1

A 'dry spray' finish defect is characterized by:

Accepted Answer

A rough, dull, or sandy texture caused by paint partially drying before reaching the surface

Answer

Dry spray occurs when atomized paint droplets partially evaporate in the air before landing, creating a rough, under-wetted surface texture.

Question 2

Resistance spot welding (RSW) on OEM-style repairs is preferred by manufacturers primarily because:

Accepted Answer

It closely replicates factory assembly welds and preserves the designed structural properties

Answer

Factory-style resistance spot welding replicates OEM joining methods, maintaining the engineered strength and deformation characteristics of the vehicle.

Question 3

Which condition would most likely cause solvent popping defects in a refinished panel?

Accepted Answer

Applying the clearcoat before the basecoat has properly flashed off

Answer

If clearcoat is applied before the basecoat has fully flashed, trapped solvents boil up through the clearcoat as it cures, creating small craters.

Question 4

When estimating refinishing for a three-stage (tri-coat) pearl finish, the estimator should account for:

Accepted Answer

Additional time for the midcoat pearl layer and increased blending complexity

Answer

Tri-coat systems have a separate pearl midcoat that must be applied and blended, significantly increasing labor and blending difficulty.

Question 5

The purpose of an adhesion promoter applied before painting a TPO (thermoplastic polyolefin) bumper is to:

Accepted Answer

Chemically bond to the non-polar plastic surface so that subsequent paint layers adhere properly

Answer

TPO is a non-polar plastic that paint does not bond to naturally; adhesion promoter modifies the surface energy to allow proper paint adhesion.
