How to repair the paintwork interface of a car so that it is not obvious? Share the operation method with us!
1. Use a polishing machine to polish the entire bottom panel (do not use 2000 sandpaper for polishing) and remove any rust and stains on the paint film.
2. Use a degreaser to remove oil and wax.
3. Grind with 2000 sandpaper, with an area about 10cm larger than the spraying scale of the base paint
4. After polishing, spray the base paint with a slightly thinner viscosity, and the spraying scale should be as small as possible
5. Spray varnish, mix the varnish proportion normally, and do not use too much pressure on the spray gun. If the spraying scale exceeds the actual color paint scale by 2cm, leave 2000 sandpaper marks of 8cm.
6. Add joint water to the varnish in a 1:1 mixture ratio
7. Spray clear paint with interface water on an 8cm scale, with a lower pressure on the spray gun. Spray gradually and be careful not to spray and hang.
8. Use 100% interface water for final connection. Spray twice, and the surrounding paint mist will evaporate along with the interface water.
9. Simply polish the gray spots in the area where the varnish is sprayed, and there is no need to pay attention to the area where the interface water is sprayed.
10. Finally, the overall polishing has been completed, and the interface will definitely not be visible after polishing.
Interface water is a high-grade diluent that must be used well.
How to distinguish the quality of interface water?
Very simple, spray the interface water onto the original car paint, blow dry it with a gun or bake it with a lamp. If the paint surface is intact and unchanged, it indicates that the interface water is usable and good.
