Is Scratch Repair Agent Effective?
2 Answers
The effect of car scratch repair fluid is similar to toothpaste, and it works quite well for minor scratches on the car's paint surface. However, if the scratches are deep, the car scratch repair fluid is basically ineffective. Therefore, when encountering minor scratches on the car's paint surface, using toothpaste might be a better option, as the effect is similar and toothpaste is readily available in almost every household, with almost no cost. Here is some relevant information: Degree of scratches: To deal with scratches, the first thing to consider is their depth, which can be classified as micro-scratches, moderate scratches, and deep scratches. Metallic paint consists of three layers from the outside to the inside: the clear coat, the base coat, and the primer. Micro-scratches: Micro-scratches refer to slight scratches on the surface paint, where the scratch penetrates the clear coat and has already damaged the base coat, but the base coat has not been completely scratched through. Some car owners, looking for a cheap option, go to non-professional roadside car washes, often resulting in scratches on the paint surface due to improper operation by the car wash workers, causing micro-scratches. The cost to repair these scratches can be higher, making it not worth the trouble.
I recently used scratch remover and found it quite effective, especially for shallow swirl marks from sunlight or minor scratches left by tree branches on car paint. The process is simple: first, clean the scratched area, let it dry, then apply the remover and gently rub with a soft cloth—the marks fade, and the paint instantly looks shinier. However, the results depend on the scratch depth—it works well for minor ones that haven't reached the primer, but if the scratch exposes white or metal, the remover is basically ineffective, and uneven application can make it look worse. After a few reapplications, I noticed its durability is limited—it wears off in one or two months during rainy seasons, requiring car wax to maintain the effect. Overall, it saves money on professional polishing for minor issues, but don’t expect a permanent fix. Before buying, choose reputable brands and test in a hidden spot to avoid color mismatch, ensuring you get the most out of it.
