What is a common consequence of oil or water contamination in paint application?

Oil or water contamination during paint application commonly leads to poor adhesion and defects in the finish. When paint is contaminated with oil or water, it disrupts the chemical bonding process that is essential for achieving a strong bond between the paint and the surface being painted. This can result in peeling, flaking, or bubbling of the paint once it dries, as the paint layer fails to adhere properly to the substrate.

Additionally, contamination can lead to surface imperfections, such as fisheyes, which are small craters in the paint film that occur when the coating is applied over contaminated surfaces. These defects not only affect the aesthetic quality of the finish but can also compromise the durability of the paint, making it more susceptible to damage from environmental factors.

In contrast, the other options presented do not accurately describe the effects of contamination. Faster drying times, enhanced gloss finish, and increased color vibrancy are not typical results of oil or water contamination; instead, they might be associated with ideal application conditions without such impurities.
