Mirka Ceramic A/O Blend Sanding Abrasives
These sanding abrasives feature a blend of sharp ceramic and aluminum oxide (A/O) grains for a faster cutting action on harder materials and offer a much longer working life compared to traditional abrasives. Ceramic abrasives tend to be slightly sharper than traditional A/O abrasives and you may wish to back down a grit to achieve a similar finish.
