How to Repair Cracked Car Paint?
2 Answers
There are two scenarios for repairing cracked car paint: 1. Treatment for minor cracks: Nipping the problem in the bud is the most effective approach. If you detect early signs of cracking on the car's surface, which is not severe, simply applying wax can resolve the issue. 2. Treatment for severe cracks: If the cracking is noticeable, exposing the primer or even causing peeling, the repair becomes more complex. It requires scraping off the peeling paint and then repainting the area. Alternatively, using a filler before repainting may be necessary.
As someone who often works on my own car repairs, I've encountered paint cracking several times. My approach is: if the cracks are shallow, first use 1500-grit sandpaper to wet sand and smooth out the raised areas, being careful not to sand too deeply. After sanding, rinse off the dust, then apply polishing compound to restore the shine—it works quite well. If the cracks are deep enough to expose the primer, you'll need to apply filler and repaint. I've tried using spray cans in my garage; before spraying, clean the surface thoroughly to ensure no stains remain, then apply thin, even coats, letting each layer dry completely before applying the next to match the color. Finish with a clear coat to protect the paint and enhance gloss. The whole process is a bit labor-intensive, but with patience, it can turn out well. For prevention, I apply hard wax monthly and park in shaded areas to avoid sun damage, extending the paint's lifespan and saving money and hassle. If unsure, it's best to go to a professional shop—they have better tools.
