This sanding stick provides 3 different grits: 320/600/4000, ideal for any task that requires a very smooth finish. Each grit area is easily identifiable by colour. The flexibility of the material easily conforms to any shape, including rounded surfaces. The coarser grit range can be used on a full range of materials including resin, metal, wood and, of course plastic. The fine 4000-grit polishing surface will allow you to refine and perfect clear plastic parts or previously painted surfaces.  For the best results, polish clear parts and previously painted surfaces as required, always gently polish to remove the glossy finish on decals.
