What is generally not a result of improper paint application and curing?

Long-lasting protection is the correct choice because it represents an outcome that is contrary to the effects of improper paint application and curing. When paint is applied correctly and allowed to cure properly, it forms a strong, durable layer that effectively protects the underlying surfaces from environmental damage, moisture, and corrosion.

In contrast, improper application methods, such as inadequate surface preparation, improper mixing of the paint, or insufficient curing time, can lead to excessive film buildup, cracking, peeling, and water spots. These issues indicate that the paint has not adhered properly or has altered its chemical structure due to improper conditions, thus compromising its effectiveness and protective qualities. Therefore, long-lasting protection is not typically associated with the consequences of improper paint application.
