How to Repair Scratches That Expose the Primer on a Car?
1 Answers
If the scratch on the car body has exposed the primer, it should be repaired at a scratch repair shop as soon as possible to prevent rusting and corrosion of the surrounding paint. 1. Minor scratches, polish to restore: If there are minor scratches accidentally, the brightness of the car paint can be restored by polishing. Use a polishing wheel with a polishing brightener to remove debris and oxidation layers attached to the car paint, smoothing out the fine scratches. 2. Deeper scratches, apply touch-up paint: If there are deeper scratches, first check if the metal surface is exposed. If the metal surface is not visible, rust will not occur, and you can carefully apply touch-up paint, dotting it with the tip of a brush, then wait for the paint to dry completely. 3. Deep and thin scratches, use colored putty: For very deep and long scratches, colored putty can be used for effective repair. Use sandpaper on the scratched area, being careful not to expand the scratched surface unnecessarily. It is important to clean the dirt thoroughly. Apply the putty carefully to ensure it fully penetrates, then apply a compound and wax.
