1. The cause of impurities
1. Spraying tools are not clean
For example, the Spray Gun is used without being cleaned effectively, and the paint container is not clean.
2. The spraying environment is not clean
Such as the spraying site is not clean, construction in windy weather, etc.
3. The base surface is not clean
If the impurities on the surface are not wiped off repeatedly, spray paint, or there are impurities in the gaps and dead corners of the repaired parts.
Spray paint before blowing clean.
4. The paint is not clean
If the paint is mixed with impurities and sprayed without filtering, etc. The remedial measures for impurities, such as the impurities in the touch-up paint on the small surface, can be washed with thinner immediately when the paint film is not dry, and then re-spray after drying. For the touch-up paint on the whole surface, when the impurity is slight, wait for the paint film to dry completely, first use sand wax to polish the impurity, and then use light wax to polish the light. If the impurities are serious, it needs to be washed with thinner and re-sprayed, or after it is completely dry, it should be smoothed with water and re-sprayed.

2. Fog marks
Refers to the circular fog marks (commonly known as repair marks) around the repaired parts of various cars after repairing, which seriously affects the appearance of the repair paint. The reasons are:
After the paint touch-up, the spit water was not sprayed in time, so that the fog mark was dried for too long, even if the spray water was sprayed, it was not easy to completely dissolve the fog mark, forming an obvious circle mark.
The properties of sprayed spit water are different from those of touch-up paint, such as the poor melting performance of spit water.
The area where the spit water is sprayed is too small, while the area of touch-up paint mist marks is too large.
The method of eliminating fog marks is relatively simple, that is, after the paint film is completely dry, use a wool polisher to apply light wax to polish it, or use a clean towel dipped in wax to wipe until the fog marks disappear.
