How to Remove Car Scratches?
1 Answers
Methods for removing car scratches are as follows: 1. Polishing and waxing to remove scratches. Generally, very fine scratches or those that haven't penetrated to the base layer can be removed through polishing. There are various methods of polishing and waxing, some of which can completely eliminate scratches, while others may still show scratches under certain conditions. Besides the pigment layer, a vehicle's paint surface also has an outermost protective layer, commonly known as the clear coat. Polishing not only removes scratches but also thins the protective layer, leading to oxidation and discoloration of the paint, and making it more susceptible to scratches from fine particles. 2. Repainting to remove scratches. For very deep scratches on metal panels that expose the metal, repainting is necessary. For less noticeable areas, touch-up painting can be used, while larger scratches require sanding off part of the paint surface before repainting. Touch-up painting involves applying paint directly to the scratch, primarily to prevent rust, so the touched-up area may look different from the surrounding paint. It may appear slightly wrinkled and not smooth, failing to blend in with the surroundings. Repainting, on the other hand, can perfectly match the surrounding paint, making it impossible to detect both the scratch and the repainted area. However, the drawbacks are quite obvious: it is expensive and takes one to two days to complete.
