Car paint: How to deal with the expansion of sandpaper marks?
Auto refinishing involves a lot of laborious processes, and it is rather simple to make mistakes with the paint surface after painting. Today, let's discuss about the enlargement of sandpaper marks. As the name suggests, it denotes that the automobile paint's surface has noticeable sanding marks. What then occurs?
1. The coarse sandpaper marks left on the bottom layer are not filled up with putty or primer.
2. Because the thinner was mixed in the wrong proportion, it will leak into the freshly applied topcoat and cause the sandpaper marks to enlarge.
3. The paint technician has subpar professional abilities. Additionally, this circumstance will arise if spray paint is applied to a vehicle paint surface that still has a lot of sand and grit on it.
If the sandpaper lines have widened, it is advised to wet or dry sand the damaged area until it is smooth, scrape putty, and then spray the automobile with primer and topcoat.
