Make old metal old.

1. First, add some coloring powder, some yellow powder and some black powder to the white paint to turn the original white paint into milky white and yellow. Instead of primer, use topcoat directly, because it needs to be polished later, so the topcoat is more wear-resistant. 2. Brush the paint twice to make it more textured and wear-resistant. Wait for it to dry. 3. Speaking of Grice, it is actually translucent brown paint, which has very good permeability, because the wood surface is uneven and there are some convex lines. After Grice is put on, the textured areas quickly absorb Grice, and the concave areas are like dirty things. 4. After going to Grice, the whole white panel turned into a big coffee face, and this thing can be done soon. 5. Then start polishing with fine sand skin, which is quite painful. At that time, I went to Grice with LG and hired two temporary coolies and painters. . . . . . . . .

Anyway, it's such a small can. 20 yuan is enough. Adding matting agent to varnish is to achieve matte effect, but it can't be adjusted too much. If it is too much, it will be shaved three times. What is the dosage? You can debug it according to your personal preference and try it on the small panel. Now the stone carving is relatively old, and the antique performance is treated as follows: 1) Brush the stone carving surface with nitric acid water or hydrochloric acid water. The surface of the stone has been corroded by chemical reaction. When it rains in the open air in summer, it looks like a cultural relic after a long time. Black and shiny due to nitric acid water or hydrochloric acid water, with a layer of wrinkled skin on it. but
