3M Sanding Sponge

These 3M softback sanding sponges with 3M micron-graded abrasives are excellent on metals. They are particularly good for reaching awkward areas on your jewellery pieces, as they're soft and flexible enabling them to conform to almost any contour.

How to use: Work up through the 2 grades starting with medium (120-180 grit) then fine (320-400 grit), then continue with your preferred final polishing method - for example polishing papers or silicon polishers.
