1, car wash

At present, car washing is generally divided into fine washing and ordinary car washing. Seemingly simple car washing can also be roughly divided into the following steps:

Inspection and cleaning of the interior of the car body, clean water cleaning of the exterior of the car body, deep cleaning of the paint surface of the car body, drying of the car body, cleaning of glass, pretreatment of mats and carpets, cleaning of the interior of the car body, polishing of tires and polishing of the surface of the car body.

2, sandpaper grinding

By judging the hardness of paint and the severity of paint surface defects, water sandpaper or pyramid sandpaper is selected to polish the scratches on the paint surface. Sandpaper mainly removes defects such as orange peel, spots, sagging, pinholes and slight scratches.

Generally, the polished paint surface is matte, and attention should be paid to the corners, ribs and light-colored parts of orange peel. Because the paint surface is thin, these parts are easily worn through by varnish, so the polishing strength should be reduced.

Pay special attention not to polish decorative strips, sealing strips, chrome-plated strips, door handles and other parts during polishing, so as not to cause unnecessary damage. If necessary, cover with adhesive tape to protect the above parts.

Step 3 amend

Select a rotary polisher with a white or orange sponge disc, and use 1500-2000 rpm for rough polishing with grinding wax.

After the coarse wax grinding step is completed, the mirror wax is used with a black sponge disc to correct the ring marks and tiny defects left in the previous step at the speed of 1500-2000 rpm, and restore the original luster of the paint surface.

4, paint protection

Waxing, polishing, coating, crystal plating and other protection for cars.
