Polishing agent is an abrasive containing finer particles of friction material. Polishing agent according to the size of the friction material particles or efficiency is divided into three kinds: small throw, medium throw and deep throw.
1. Micro casting has the dual effect of removing slight oxidation layer and waxing care, and is used to remove extremely subtle paint film damage, such as environmental pollution and acid erosion, but this kind of slight damage, wax containing polishing agent can be used to replace micro casting. As the last process of polishing, micro-casting can be completed by hand, which can avoid uneven polishing, halo and other phenomena and have brightening effect.
2. Medium casting can remove moderate oxide layer and mild scratches of paint film. It does not contain silicon and wax, can be used with polishing machine, the oil contained in paint film polishing at the same time into the paint to supplement the paint lost oil, play a role in nursing brightening.
3. Deep casting can remove the thick oxide layer of paint film, scratches and "pitting", "hanging" and so on. It is silicon - and wax-free and is used with a polishing machine.
Medium casting and deep casting are mainly used to deal with different degrees of hair scratches. Medium casting is mainly suitable for polishing varnish, deep casting is mainly suitable for polishing ordinary paint.
