4" x 36" Schwarz, wasserdicht, ohne Körnung, zum Polieren

Using this on a rotary tool for finishing touches on aluminum—the 4x36 size gives me enough material to last through several projects without constantly swapping sheets. The waterproof backing holds up well when I need to keep it wet, and it leaves a smooth result without leaving any grit behind.

The black waterproof backing handled the wet polishing session without curling or falling apart, which was my main worry. Cut a strip off and it stayed true to size with no fraying at the edges. Exactly what I needed for the final pass.

The roll is exactly 4"x36" as listed, and the waterproof backing seems sturdy enough for wet polishing work. Only gripe is it's a bit stiff out of the package, but it flexes fine once you get going.
