The polishing pad is a unique polishing pad, like a fish scale, designed by senior with many years of car beauty experience. The groove can excess polishing paste and abrasive; at the same time, it accelerates the air circulation between the paint and the polishing pad, thereby avoiding heat accumulation; Using high-density polyurethane sponge, it feels beautiful, soft and easy to bend. Uniform pore size, high air permeability, and tensile strength enhance the polishing pad; Using high- Buckle, high air permeability. Therefore, the working heat can be released from the buckle to avoid bonding failure caused by heat accumulation on the back. The high- waterproof adhesive is used between the sponge and the Buckle, which has a long service life and strong stability, and has strong stickiness after repeated use for hundreds of ; Therefore, during the polishing process, the sponge surface is prevented from being scratched and scorched, reducing the wear between the sponge and the fastener, and improving the reliability of the product. The cutting mat can fully and evenly distribute the ultra-fine abrasive reagent particles, and the effect is long-lasting. Product hardness difference: (black, blue and white) yellow orange, can eliminate the corresponding mild, neutral and severe scratches.
