What is the purpose of using a heat gun in paint repair?

Using a heat gun in paint repair serves several valuable functions, one of which is to remove wrinkles or waves in the paint without compromising its integrity. When paint is applied, various factors such as temperature and humidity can cause the paint to wrinkle or form waves as it dries. A heat gun provides a controlled heat source that can gently warm the paint, allowing it to relax and flatten out, helping to restore a smooth finish.

This technique is particularly advantageous because it helps to correct surface imperfections without stripping away the paint or damaging the underlying material. By carefully applying heat, the paint can be reshaped as it becomes more pliable, achieving a much more even and professional appearance.

While other options mention baking paint faster, softening paint for removal, or speeding up the curing process, these functions do not align specifically with the context of addressing surface imperfections in paint repair. The focus on maintaining the integrity of the paint while removing defects is what distinguishes this correct purpose for using a heat gun.
