がすぐれているので好ましい。A disk sander is an instrument for circularly moving a disk on which abrasive paper (cloth) is stuck, and polishing an object surface with the abrasive paper. A known one can be used in the present invention. Suitably, the disc is flat with a radius of about 5 to about 10 cm and a thickness of about 1 to about 5 mm. Abrasive paper (cloth) to be adhered to the disk surface is made by gluing abrasive particles such as fused alumina, silicon carbide, emery, garnet, and quartzite on cloth or paper, and using an adhesive of gelatin or synthetic resin. Adhered, particle size is # 240 to # 3 according to JISR6001
A range of 20 is suitable. There are an electric drive type and an air drive type as such a disk sander. The air drive type has a small load on the sander and excellent workability even when pressing the polishing disc while rotating it on an elastic plastic part. Is preferred.

い。According to the method of the present invention, the plastic part is rotated while pressing the disk sander on the scratched part on the outer surface of the plastic part as it is mounted on the vehicle body and the peripheral part in the vicinity thereof. A rotation speed of 1,000 to 10,000 rotations per minute is suitable. Due to the frictional heat generated by the rotation of the sander, the temperature of the scratched part of the plastic part and the surrounding area rises, and after a few minutes, these parts soften and melt,
Eventually, the cracks and crevices of the flaws join to achieve the present invention. Due to this frictional heat, the temperature of that part is 50
℃ or higher. These operations are
The plastic parts may be removed from the vehicle body.

When the surface of an air-driven disk sander (radius of about 8 cm) to which abrasive paper having a grain size of # 280 is adhered is applied and the disk is rotated while being pressed against a bumper (rotation speed is 3000 times per minute), the frictional heat is generated. As a result, the temperature of the plastic at the location of the scratch and the surrounding area rises, and after a few minutes, these portions soften, further partially melt, and the cracks in the scratch portion are joined and closed, thereby achieving the present invention. . . Due to this frictional heat, the temperature of the portion was 80 ° C. or more. The time required from the start to the end of this operation was about 3 minutes.
