Meguiar's Mirror Glaze Unigrit Finishing Paper is a 3000 grit sandpaper with uniform grit particles that leave a smooth, even sanding pattern that buffs out in seconds, eliminating the risk of deep sanding scratches that require aggressive compounds to remove. This car sandpaper works faster and lasts longer than conventional sanding products, and it doesn't load up as quickly, making it an economical choice for your car care toolkit. Sandpaper is waterproof and safe to use on all paint finishes and clear coats.
