A few months ago, Cabinetmaker magazine published a true/false quiz about glue, written by Gene Wengert, who has probably done more than anyone in the last 30 years to educate us about wood and adhesives. I enjoyed taking the “test” and, with full credit to Gene for the idea, I’m adapting it for finishing.

If you’ve been reading this column regularly, you should do very well.

1. All solvents for finishes are classified as VOCs. True or False?

2. Water-based lacquer is an emulsified form of nitrocellulose lacquer with all the same properties. True or False?

3. The primary way to reduce orange peel is to increase air pressure, thin the finish or both. True or False?

4. The most important instruction to follow when spraying a finish is to watch what’s happening in a reflected light. True or False?
