SMAT or DAT

There are mainly 2 different types of polishes. SMAT and DAT. Knowing which one does what will help you to choose the right polish for the job.

SMAT and DAT

polish is made out of a few ingredients. Most common is an oil to help lubricate and an abrasive material (usually a powdery substance).
SMAT = Super Micro abrasive Technology
SMAT uses micro abrasives of a fixed size for a controlled and even effect. These abrasives stay this size. Which means that more passes will have more effect. In essence: the longer you polish, the more effect it will have (because you remove more paint). There is a limit to how long it lasts because the micro abrasives in the polish can be deformed by the polishing-action, making them less effective. Stop polishing when you have achieved the desired result.
DAT = Diminishing abrasives Technology
DAT uses abrasives that break down while using. A combination of pressure, heat and time causes the abrasives in the polish to become smaller and smaller. They get pulverized and disintegrate into nothing. After a certain time, the polish will have no effect anymore, regardless of the passes you make. It is highly recommended to work in the polish until it is completely disintegrated.
DAT may offer less cutting power then SMAT, but they finish with a surface that needs much less refinement. In some cases you can actually achieve a finishing result with 1 polish.
