A metal surface filling and leveling agent. The metal surface filling and leveling agent comprises the components in parts by weight: main materials: 20 to 40 parts of bonding agent, 60 to 80 parts of 200-to-1200-mesh metal powder, 1 to 5 parts of styrene, 1 to 4 parts of promoter and 1 to 5 parts of assistant; and curing agents：1 to 6 parts of initiator and 1 to 6 parts of filler. The main materials and the curing agents are separately packaged, and can be mixed according to a certain proportion in use. By using the metal surface filling and leveling agent prepared according to the formula, the impact resistance performance, strength and hardness of a metal surface are improved, the shrinkage is smaller, the drying speed is high, and the temperature resistance is good; the polished metal surface completely has the sense of metal and unique light quality of metal, and has good appearance.
