2. Sandpaper grinding: By judging the hardness of paint and the severity of paint surface defects, sandpaper mainly removes defects such as orange peel, spots, sagging, pinholes and slight scratches. When sanding, it should be evenly applied. Generally, the polished paint surface is matte, and attention should be paid to corners, ridges and areas with light orange peel. Due to the thin paint surface, these parts are easy to wear through varnish, and the grinding strength should be reduced appropriately. It is especially important to note that when polishing, do not polish decorative strips, sealing strips, chrome-plated strips, door handles and other parts to avoid unnecessary damage. If necessary, cover the above parts with adhesive tape;
3. Polishing: Select a rotary polisher with a white or orange sponge disc, and use 1500-2000 rpm for rough polishing with grinding wax. The effect of coarse wax grinding is the best in the initial grinding, and the pressure should be moderate during construction, and then relaxed appropriately, and the pressure should be moderate during construction. Don't blindly pursue speed, blindly improve speed. If the speed is too fast, it is easy to cause the paint to be thrown through and cause irreversible damage to the paint.
