White Hard Pad Plus 150mm Smirdex 951.

Features:
White Open-cell foam ideal for Fast Cutting and Polishing.
This very hard pad consists of a foam that changes its properties when exposed to heat.
Its hardness depends on temperature to a great extent.
Initially the foam is very hard to the touch, but as soon as it is warmed up, it softens up to a certain level.
The foam becomes so soft that it is recommended to use it for cutting and polishing.
Combining the 923 Heavy Cut Polishing compound onto the white very hard pad you get a high level of buffing in addition to a very nice gloss and finish.
