P240 grit is the finest small rubbing block available.
The abrasive grain is bonded into a flexible rubber matrix which gives it a soft action in contact with the workpiece.
The P240 grit rubbing block will remove hairline scratches and is most commonly uised for blending super fine satin finishes.
Note: We recommend the 30 and 60 grade for blending the grain on box / 240 grit stainless steel tube
