Does a Full Car Polish Cause Significant Damage?
2 Answers
Occasional full car polishing once or twice does not cause damage, but it is not recommended to do it frequently as polishing may thin the car paint. Notes on polishing are as follows: Use coarser abrasives: The key to operating a polishing machine is to achieve the maximum polishing rate to quickly remove the damaged layer caused by grinding. Coarser abrasives are required to ensure a higher polishing rate to eliminate the grinding damage layer, but the polishing damage layer is also deeper. Rough polishing: The goal is to remove the grinding damage layer. This stage should have the highest polishing rate, with the surface damage caused by rough polishing being a secondary consideration, but it should still be minimized as much as possible. Fine polishing: The purpose is to remove the surface damage caused by rough polishing, minimizing the polishing damage.
I think a full car polish doesn't cause much damage to the car, as long as it's done properly and the frequency is controlled. Polishing mainly involves using a machine to lightly buff away scratches or oxidation on the paint surface, restoring the car's shine, but it does slightly thin the paint layer; the one-time damage is minimal and basically negligible. I often polish my car myself, using appropriate polishing compounds and soft pads to avoid excessive wear. If the paint is thick, especially on a new car, one polishing session is generally fine; but for older cars or those with thin paint, you need to be careful to avoid exposing the metal to rust. It's recommended to polish only when there are stubborn stains or obvious aging, with a frequency of once every two to three years being sufficient. After polishing, remember to apply wax or sealant, which forms a protective layer and reduces external damage. Regular washing to keep the car clean can also extend the intervals between polishing, ensuring the paint remains healthy and the appearance lasts longer.
