Meguiar's¨ Mirror Glaze¨ Unigrit¨ Finishing Paper uses uniform grit particles to leave a smooth, even sanding pattern that buffs out in seconds, eliminating the risk of deep sanding scratches that require compounds to remove. It works faster and lasts longer than conventional sanding products, and doesn't load up as quickly. This paper is waterproof and safe for use on all paint finishes and clear coats.
