3M auto care Rubbing compound revives the luster and shine that makes a car glisten out on a sunny day. Our automotive rubbing compound both smooth's and cleans surfaces, making it a dual purpose product. Compounding removes the scratch pattern left by abrasives in previous sanding applications. You can expect it to effectively remove fine sanding scratches in the gelcoat. While smoothing the surface, it also cleans by removing oxidation, water spots and other stains and blemishes. Our rubbing compound for cars produces a high quality professional finish that helps reduce the appearance of coarse swirl marks. Its fast cut formulation reduces compounding time, making restoration a quicker and easier task.
