Layer 1: bare metal (thoroughly cleaned to increase corrosion resistance and adhesion of primer)
The second layer: epoxy primer (fused on the metal surface to provide excellent adhesion and rust resistance)
Layer 3: sheet metal ash (used to fill the depression after sheet metal shaping, with very strong hardness and toughness)
Layer 4: intermediate primer (providing excellent filling, sealing and polishing, good adhesion with the subsequent coating, and setting off the fullness of the finish coat)
