In the process of repairing the painting work of the body, the grinding work runs through and is the ultimate guarantee of the quality of the painting. This article will comprehensively describe the use and precautions of abrasive tools in the process of car refinishing . It is believed that it will help auto repair technicians to improve sheet metal spraying technology and improve the quality of repairs . Topcoat polishing is mainly aimed at the polishing of fine defects such as particles, fibers, and pinholes on the surface of the topcoat body. The topcoat grinding  is different from the middle coating or electrophoresis body grind ing. Provides higher decorative properties; so the requirements for topcoat grin ding are also higher than those for midcoat or electrophoretic body sanding.   There are some tips for topcoat grinding below: 1. For topcoat grind ing, P1200 # , P1500# or even P2000#  sandpaper should be used and soaked in water for 3~5min. The fineness of the ...

The coating s   come up with   the overall coverage of abrasive grain particles (such as aluminum oxide or silicon carbide) which are attached to   the backing material of coated abrasive   product, or rather, how much space is filled or not filled with abrasive grains.   The more open space there is between grains, combined with the constant motion from sanding, can lead to a longer abrasive life. As the sandpaper   sheet   is used   in a more open coat allows the residue to fall off, thus making it less likely to get stuck in between the grains. Not to mention, the extra space allows more room for air to flow, thereby cooling down the sand ing disc   during the sanding process. U ltimately, with less heat, there will be less opportunity for the wood resins and finish to soften in the first place.   There are   three form s of coating options available: open, semi-open and closed   -   Each type has a different particle r...

In order to prevent the appearance of the car from being damaged, many car owners sanded  and polish ed  the car  by themselves , so that the appearance of the car can be neat and generous, and it can also prevent the car from rusting and bumping. N ow , we will share with you 3 methods of sand ing and polishing.   The first is to hard remove the fine scratches by the force of sanding  and friction material . The second is to rely on the effect of wax, after polishing to a certain extent, rely on the luster of wax to make up for the defects of polishing.   The last one relies on chemical reaction, that is, the chemical reaction produced by the polishing agent by adjusting the rotation speed of the polishing machine. The abrasive particles of physical san ding are choose different sanding disc and  sandpaper sheet , with coarse, medium and fine grades, and the deoxidation and scratch effects are quite good , i t is the mainstream san ding and polishing ...
