Sample Questions

Question 1
Which type of primer should be applied directly to bare steel to ensure the best corrosion resistance and adhesion?
Waterborne basecoat
High-build acrylic primer
Wash primer
Epoxy primer
Question 2
What is the primary purpose of using a solvent-based wax and grease remover prior to sanding a vehicle panel?
To act as a guide coat during block sanding
To chemically etch the surface for better mechanical adhesion
To prevent grinding contaminants into the substrate sanding scratches
To increase the paint thickness of the substrate
Question 3
Which of the following is critical when preparing bare aluminum panels for refinishing compared to steel panels?
Use heavy-duty wire brushes to create a deep mechanical profile
Wash the aluminum surface with a strong sodium hydroxide solution
Use only dedicated aluminum abrasives and clean tools to prevent cross-contamination
Apply polyester body filler directly to the raw aluminum without priming
Question 4
What prep step is required on raw polypropylene (PP) plastic bumpers to ensure subsequent coatings adhere?
Etch the plastic with phosphoric acid solution
Sand the surface using coarse 80-grit sandpaper to create a rough profile
Apply a heavy coat of standard metal epoxy primer
Apply a dedicated plastic adhesion promoter after thorough cleaning and scuffing
Question 5
How can a technician identify if an unmarked plastic panel is a polyolefin (e.g., PP) or a non-polyolefin (e.g., ABS) using a float test?
Place a drop of solvent on the plastic; polyolefins will float or repel the solvent droplet
Submerge the plastic in water; if it sinks rapidly, it is a polyolefin
Heat the plastic with a hot air gun; polyolefins will float away as liquid vapor
Cut a small piece of the plastic and see if it floats in water; polyolefins float because their density is less than 1.0 g/cm³
