How to Deal with Full Car Scratches?
2 Answers
Methods for handling full car scratches are as follows: 1. Sand the dent. Locate the car scratch, clean it with water first, wipe it dry with a cloth, and use 800-grit sandpaper to sand the scratch. You can sand while rinsing with water or soak the sandpaper before sanding to remove rust, oxides, dust, etc. from the scratch. 2. Fill with putty. Squeeze an appropriate amount of putty onto a scraper and apply it to the scratch. Quickly and firmly spread the putty over the scratch, ensuring it adheres tightly. Wait about ten minutes before proceeding to the next step. 3. Sand the putty. Use 2000-grit sandpaper to sand the putty area while rinsing with water until the putty is level with the surrounding paint. Wipe the area dry with a cloth before painting. 4. Paint. Before painting, protect the car's paint surface by using newspapers secured in the door gaps. Avoid protecting too close to the scratch to prevent obvious dividing lines after painting. Try to expand the protection area. 5. Apply gloss clear coat. Apply the gloss clear coat one to two hours after painting. The method is similar to painting, and it's best to apply two to three layers, but avoid applying too much. 6. Apply blending clear coat. Five minutes after completing the above steps, apply the blending clear coat to the junction between the new and old paint surfaces to prevent noticeable gaps. One layer is sufficient.
My car got maliciously scratched all around last month, it was heartbreaking. If it's just minor surface scratches, you can try scratch wax and polishing compound to handle it yourself. First, thoroughly wash the car body, then use a soft cloth dipped in a bit of abrasive to gently polish the scratched area, but don't press too hard to avoid damaging the original paint. For deeper scratches, you'll need a professional to do the touch-up painting. They will sand the entire area, fill it, repaint, and bake it. Some more meticulous shops can even achieve a color match. If the scratch is deep enough to expose the primer, don't delay fixing it, otherwise rain can cause rust and corrode the steel plate. Nowadays, some car owners opt for a full-body color-changing wrap, which both covers the scratches and adds personality, but make sure to choose high-quality TPU material film for durability. After repairing the paint, remember to regularly wax it for protection, as the repaired original paint won't be as resistant to aging as before.
