Top 10 Car Paint Repair Mistakes
1. Not removing dirt and wax before paint touch-up.
Applying touch up paint on top of a dirty surface will prevent it from adhering properly. First, you need to wash it with water and some dish soap. Next, follow it up with prep solvent. Prep solvent removes oils, road grease, dirt, car wax, and other surface contaminates and also improves adhesion to the surface.
2. Painting in the wrong temperatures.
Painting your car in the temperatures lower than 55F or higher than 80F is not a good idea. As the weather gets colder or hotter, the behavior of the paint changes which might result in blotches or blushing, bubbling, discoloration, or a gritty texture. The ideal temperature is 72F with 50% humidity.
3. Using wrong sandpaper.
You need to use sandpaper specially designed for car paint repairs. Regular wood sandpaper or sanding block is too rough and will leave scratches. If you want to do wet sanding, make sure it says wet/dry on the label. (more…)
