3M™ paint and rust stripper works quicker, lasts longer and cuts faster than conventional sandpaper to strip away corrosion, scale and old finishes. Made from durable, non-woven synthetic material, rust and paint remover makes a tough job faster and easier - it cleans away surface corrosion to reveal the surface below. Silicon carbide abrasives fracture easily to expose sharp edges for aggressive grinding that speeds removal of rust and scale. The paint and rust stripper may be used on fiberboard, plastics, wood, clear coat, fiberglass, filler, metal, paint and putty. Simply attach this disc to an electric drill with a 1/4 in mandrel and apply directly to corrosion or old paint for fast removal. The power of the electric drill saves a lot of time and effort compared with sanding by hand.
