Question

Quizplus · Accepted Answer

Enamel finishes typically harden through a combination of solvent evaporation and oxidation, which causes the paint to form a hard, durable coating. Urethane paint, on the other hand, typically dries through a process of solvent evaporation and/or chemical cross-linking. Therefore, Technician A is correct while Technician B is incorrect.
