If you rub the painted surface lightly, you will often leave white stripes where the nails are nailed in the shallow grooves. In addition, in some cases, only foreign objects (such as paint fragments) are attached. If it is a protruding scratch, the color is obviously different from Hoddy's, there is no doubt about it. Both cases can be completely removed by polishing with a fine compound for mirror polishing.

1. Soak the sponge in water and squeeze it.

Yes, if you choose the wrong tool, it will be scratched. When polishing, it is best to use wax sponge made of natural paper pulp as "cellulose" or porous "PVA foam" because it has good water retention, so it can prevent the compound from being cut by friction heat. In addition, wipe with a soft "lint-free cloth". Both of them can be bought in auto supplies stores, so I want to get them ready.

By the way, although cellulose fiber and PVA sponge have good water absorption, they will become as hard as stone after drying. Therefore, it is very important to keep moist during storage. When it is used, it should be immersed in water every time, until it becomes soft, and then squeezed.

Apply a fine mixture

Prepare a "mirror paint" or "superfine" compound, and then squeeze the amount around the tip of the little finger out of the sponge.

Hit evenly with a pompon.

Gently press billiards on the surface to be polished of the sponge with the compound attached for 2-3 times, and then evenly apply the compound.

4. Polishing parallel to scratches

Move the sponge along a straight line parallel to the scratch, and then roughly polish it. If you wipe 10 times or so, avoid overexertion on the surface other than the scraping surface, and the paragraph will become a paragraph.

5. Wipe to check scratches.

Wipe off the scratches with flannel cloth. If it is still outstanding, add a small amount of compound and grind it again to check the surface effect. Repeat this process and gradually delete it.

This is done! It should be noted that even if "fine" is used, there is no difference in polishing with this compound. So grinding too much will fade; If the limit is exceeded, the background color will appear, so be careful! Generally speaking, "step by step" is the principle when observing the situation. I want to stop working immediately when the luster is a little dark.

When polishing, it reciprocates parallel to the scratch line. If polished in a circular way, scratches will be scratched and the surface will be uneven, so even if it is polished, it will move in a straight line. In addition, the work is carried out in the shadow in principle, so it is important to ensure that the painted surface is fully cooled when starting.
