What is one consequence of using a thinner that evaporates too quickly?

Using a thinner that evaporates too quickly can lead to "orange-peel" issues in the finished surface of a paint job. This phenomenon occurs because rapid evaporation does not allow sufficient time for the paint to level out properly before it begins to dry. As a result, the surface may develop a textured appearance that resembles the skin of an orange, which is undesirable in most finishing applications.

While thinner that evaporates quickly might accelerate the application process, it compromises the quality of the finish by preventing the paint from achieving a smooth, even surface. The other options, such as improved gloss finish, faster application rate, and reduced toxicity risks, do not accurately describe the downside of using a high evaporation rate thinner in the context of surface finish quality.
