The mixture is strictly proportional and stirred evenly until there is no color difference.
III. Smudge material
Apply the uniform 2211F to the scratch surface.
IV. Curing
The temperature can be increased by a halogen tungsten lamp. For each temperature increase of 11 °C, the curing time will be shortened by half, and the optimal curing temperature will be 70 °C. After the material is cured, the material on the surface of Gaochu is repaired with fine grinding stone or scraper.
