Treating surface damage on the flat chested sex doll requires patience and meticulous work. Shallow scratches can be gradually smoothed out with silicone polish, while deeper damage requires filling with specialized filler and then smoothing. When repairing a life size sex doll, ensure the overall skin texture is consistent, and the newly repaired area should match the texture of the surrounding skin. For the flat areas typically found on flat chested sex dolls, special care must be taken to maintain the natural curvature of the surface during repair to avoid unnatural flatness or bulges. It's recommended to compare colors under natural light, using small amounts of pigment to gradually adjust the color until the new and old materials blend completely. After each operation, allow the material to fully cure for 24 hours before proceeding.
