How to polish your car with abrasive paper?

First, use a paint surface cleaner with strong decontamination ability to clean the whole car to prevent secondary damage to the car body caused by particle dust during grinding. Before polishing, use 600# to 1000# water sandpaper dipped in water to wrap the small rubber lining block, and lightly sand the traces until the surface is flat. Be careful not to wear through the paint layer. Then use the machine grinder to add coarse grinding paste to rough-grind the traces of the water sandpaper, and then add the grinding paste to start polishing and fine grinding. Use a mechanical polishing machine and add a mirror treatment agent to remove the traces left by the coarse grinding paste to achieve the effect of mirror polishing of the paint film. After grinding and polishing is completed, wipe off the grinding and polishing paste, and immediately use cotton yarn dipped in varnish wax to wipe the polished part as a whole, and then use dry cotton yarn to wipe off the excess glazing wax, so that the paint surface is bright and dazzling like a mirror.

How to check whether the paint treatment is successful? Place a piece of newspaper on the paint surface of the car. If you can see the lettering of the newspaper in the reflection of the paint, it means that the clear paint of this car has a deep shadow and the surface is smooth like a mirror.
