Pass the test! (28 cards)
Who regulates hazardous waste in refinishing?
Federal, state, and local governments regulate hazardous waste.
Why must hazardous waste be stored according to fire, building, and electrical codes?
To prevent fires, spills, and environmental contamination.
Is a shop responsible for hazardous waste after it’s hauled away?
Yes, the shop remains liable if the waste is improperly handled.
Do containers smaller than 5 gallons need to be grounded?
Yes, to prevent static sparks and fire hazards.
What is the ‘Three-Ounce Cup Rule’?
Only three ounces of paint can be sprayed if it contains hazardous air pollutants.
Why is it important that G360 compounds have no fillers?
Fillers can hide defects instead of permanently correcting them.
Should you use a large or small amount of G360 Super Fast Compound?
A small amount—too much can create residue and waste.
What is the ideal RPM range for polishing?
1500-1800 RPM for main polishing, increasing speed for final passes.
What causes paint etching?
Bird droppings, tar, and tree sap cause chemical damage to paint.
Does polishing remove defects permanently?
Only if they are in the clear coat; deeper damage requires repainting.
What does the fluid tip on a spray gun do?
It atomizes the paint for even application.
What happens if a spray gun is too far from the surface?
The paint partially dries before hitting the surface, leading to poor adhesion.
What is ‘arcing’ in spray painting?
Tilting the spray gun, causing uneven coverage.
Why must OSHA respirator cartridges be stored in airtight containers?
To prevent exposure to air, which degrades their filtering ability.
When is etch primer needed?
For bare metal areas larger than 5” x 5” to prevent corrosion.
Why is flash time important between coats?
Skipping it traps solvents, leading to paint failure.
How long does SpectraPrime surfacer take to air dry?
2-3 hours at 70°F or force dry at 140°F.
Why use different reducers in hot vs. cold weather?
Hot weather needs slower reducers; cold weather needs faster reducers.
Can Ultra 9K waterborne paint be shaken?
No, it must be agitated by hand to prevent bubbles.
What happens if clearcoat is applied too soon?
Trapped moisture causes defects in the finish.
Why does Ultra 9K have a bluish tint when applied?
This tint disappears once the paint dehydrates.
How many coats of clearcoat should be applied?
Two coats—one is not enough for proper protection.
Why use finer grit sandpaper for spot repairs?
Prevents burning through the clear coat.
What is the ‘picture framing effect’ in painting?
Extra material collects on edges, creating an uneven surface.
