No matter how deep or shallow the vortex marks are, it can be said that most of them are caused by unscientific cleaning. When sufficient pre-washing is not carried out, and the gloves are not cleaned during the whole process of scrubbing the body, there is a great chance that this kind of bad situation will occur.
This kind of problem is not too conspicuous in daily life, but when the sun shines on the car body, it will show traces like fine cobwebs, so we can make these traces invisible through the trapping light during the polishing process.
