ASE Painting & Refinishing 3

Question 1

Orange peel texture in a clearcoat is most often the result of what?

Accepted Answer

Improper atomization, high viscosity, or insufficient flow-out

Answer

Poor atomization or thick material prevents the clear from leveling, leaving a peel-like texture.

Question 2

Before applying basecoat, why is a tack cloth used?

Accepted Answer

To remove dust and lint from the surface

Answer

A tack cloth lifts loose dust and lint just before painting to prevent contamination in the finish.

Question 3

What does HVLP stand for in spray gun technology?

Accepted Answer

High Volume Low Pressure

Answer

HVLP guns deliver a high volume of air at low pressure for better transfer efficiency and less overspray.

Question 4

Solvent popping (small craters) in a cured film usually indicates what?

Accepted Answer

Solvents trapped under the surface from coats too heavy or baked too soon

Answer

Heavy coats or premature baking trap solvent that bursts through, causing pinholes and craters.

Question 5

When blending a basecoat into an adjacent panel, the main goal is to:

Accepted Answer

Gradually feather the new color so the transition is invisible

Answer

Blending feathers the color outward so the eye cannot detect where new meets old.
