Why is BMW's paint so thin?

[LeLevi]

BMW's paint is approximately 1/4 to 1/5 thinner than that of European and American car models. A representative brand is Nissan, which also has relatively thin paint. Generally, driving at high speeds can easily cause small pinholes in the paint surface. Methods for dealing with scratches on the car are as follows: 1. Hairline scratches: Hairline scratches can usually be removed by polishing or applying a rubbing compound. A light wipe is often enough to make the hairline scratches disappear. 2. Light scratches: For light scratches, simply prepare a tube of toothpaste. Toothpaste is very effective for shallow scratches that haven't damaged the car's primer, especially for marks left by other vehicles' paint during minor collisions or residues from sticky products like adhesive tape. Most of these marks can be wiped away completely. 3. Moderate to deep scratches: Moderate and deep scratches cannot be repaired by polishing. If the dent is small and does not exceed 5mm, it can be filled with putty to level the surface, followed by touch-up paint.
