※ polishing agent type can be divided into
① coarse polishing agent: contains small particles, can remove the depth of oxide layer and slight scratches and painted pitting and so on.
② polishing agent: thinner than the rough particles can remove the slight scratch paint.
③ reducing agent: ultrafine, increase the brightness of the paint, restore the original luster of the paint.
Note: Do not think the larger the particle, the stronger the ability of the abrasive, the Japanese abrasive because of the high alumina composition, to make the abrasive ultrafine, but the ability to scratch is very strong.
