How to Repair Scratched Car Paint?
2 Answers
Minor scratches on car paint can be repaired using fine polishing wax. The principle involves rearranging the molecules of the surface paint layer, effectively moving adjacent surface paint to cover the scratch. Below is an introduction to car paint scratches: 1. The role of the paint film: Car paint must have a paint film with good mechanical properties, excellent fullness, and high gloss. It should also possess strong adhesion, high hardness, and scratch resistance, along with good weather resistance, wear resistance, gloss retention, and resistance to gasoline, alcohol, acid, alkali, and salt spray. 2. Precautions: Unless absolutely necessary, avoid repainting body scratches. This is because the original factory paint includes an electrophoretic layer, which is absent in repainted areas. The lack of an electrophoretic layer can lead to poor adhesion, noticeable color differences, and other issues. Additionally, the original factory paint has more advanced application techniques, resulting in significantly better quality compared to repainted areas.
When I notice scratches on the car paint, I handle them based on the depth of the scratches. For shallow scratches, I first clean off the dirt with soapy water, then dry it with a soft cloth to prevent debris from entering the scratch and worsening the damage. Next, I buy a scratch repair wax or polish, apply it evenly with a sponge, and rub firmly for a few minutes until the scratch becomes invisible or fades. For deeper scratches, I use a touch-up pen—first checking the vehicle's color code to ensure a match—and carefully apply it layer by layer. After it dries, I apply a clear coat for protection. The key is to take it step by step and not rush, as haste can cause bumps or unevenness in the repair. After fixing, I wax the car monthly to prevent oxidation and keep it looking new. When parking, I avoid areas near branches or narrow spaces to minimize minor scrapes. Tools are affordable online and suitable for DIY enthusiasts like me. Remember, patience is key—don’t damage the original paint. This DIY approach saves money and time while honing my hands-on skills.
