How often may and should paint be polished?
Basically, a polish only treats the car’s clear coat. This is approx. 30 µm thick. A very intensive manual application – e.g. with SONAX Xtreme Polish & Wax 3 – can “sand down” a maximum of 0.3 µm of the clear coat. This means that the paint endures up to 100 applications without any problem. However, it is recommended to be careful when using a polishing machine: too high pressure can sand down the paint layer completely – particularly on edges and folds.
