1. After the substrate is processed, do not use #2000 sandpaper to polish directly. Use a polishing machine to polish the entire panel to remove the rust and stains on the paint film.
2. Use a degreaser agent to remove the oil and clean up the wax.
3. Use #2000 sandpaper to polish, and the polished area needs to be about 10 cm larger according to the spraying range of the base paint.
4. After polishing with sandpaper, spray the base paint, the viscosity of the base paint should be a little thinner, and the spraying range should be as small as possible.
5. Spray the varnish, the varnish ratio is normal to mix with hardener, and the air pressure of the spray gun should not be too heavy. The spraying range is 2 cm beyond the color paint range, leaving 8cm #2000 sandpaper traces.
6. Add the varnish to the thinner SRA, the mixing ratio is 1:1.
7. Spray the ready-mix of varnish and thinner SRA in the range of 8cm. The air pressure of the spray gun should be lower, and should be sprayed little by little.
8. Use 100% thinner SRA for final connection. Spray twice, the surrounding paint mist will volatilize along with the thinner SRA.
9. Simply polish the gray spots where the varnish is sprayed, and leave it alone where there is thinner SRA.
10. The final step is overall polishing, and the touch-up interface is absolutely invisible after polishing.
The thinner SRA is a high-grade thinner and must be used well.
How to judge whether the thinner SRA is good or bad?
It's very simple. Spray the original car paint with thinner SRA, blow it dry with a gun or bake it with a lamp. If the paint surface is intact, it means that the thinner SRA can be used and it is good.
