The main component of polishing wax is water-soluble wax (also oily wax) abrasive particles, which are generally divided into several grades according to the thickness of the abrasive particles.

1. Coarse wax is also called grinding wax. Its main function is to grind the polished part of fine sandpaper (P 1000-P15000 dry grinding or P 2000 water mill) in more detail to eliminate the traces of abrasive paper and make the paint film brighter. Or use when good light loss old paint is polished and beautified. Polishing coarse wax needs to be used in conjunction with the use of the hair wheel, which has a good grinding effect on the grinding part of the fine sandpaper. However, although the wear marks of the sandpaper are eliminated after grinding, the abrasive grains are coarser, and the wear marks of the sandpaper are eliminated after grinding. When the brightness of the paint film still needs to be sanded with medium or fine wax.

2. The abrasive particles of medium coarse wax are much finer than that of coarse wax, the paint film after grinding is bright, and the bright basically does not require other polishing treatments.

However, the use of medium and coarse wax to directly grind the grinding part of the sandpaper or the polished old paint surface has lower production efficiency, and a smaller polishing operation range can be formed at one time, but when polishing a large area, first use coarse wax for grinding cut. The secondary polishing effect of medium and coarse wax is better and the efficiency is higher.

3. Crude wax is the most commonly used product for automotive refinish coatings.

4. The polishing effect of fine wax is better than other grinding effects. It is mainly used for the final polishing treatment of high-end cars and the polishing and beauty work of general small scratches . Fine waxes are often used with sponge grinding wheels and receive the wax as they grind. The final result is reflection and freshness.
