This is a sanding disc designed for mattening and paint rectification of top- and clear-coat applications. Model Number: FM-622-2000. It is aimed at automotive refinishing users, marine shops, composite work, and wood processing jobs where a controlled scratch pattern matters more than aggressive stock removal.\u003c\/p\u003e\n      \u003cp\u003eWhat makes the Microstar line useful is how it handles delicate finishing work. Mirka states that this abrasive produces a fine scratch pattern that is easier to polish out, which is exactly what you want when you are trying to save time between sanding and final finishing. Instead of fighting deep scratches or uneven cut, you get a more predictable surface that is better suited for follow-up polishing and correction steps.\u003c\/p\u003e\n      \u003cp\u003eThe disc uses aluminum oxide grain on a polyester film backing. That combination matters because film-backed abrasives tend to stay more consistent than paper-backed options in precision finishing applications. For the user, that means steadier contact, cleaner feel on the sander, and less chance of the disc breaking down too quickly during detail work.\u003c\/p\u003e\n      \u003cp\u003eMirka also calls out a special stearate layer and a semi-open coating. In plain terms, that setup is there to help the disc resist clogging compared to more traditional abrasives. When you are sanding coatings and finishes, loading is one of the fastest ways to slow down the job and ruin consistency. A disc that stays cleaner longer helps maintain cut quality and reduces wasted abrasives.\u003c\/p\u003e\n      \u003cp\u003eThis is a grip disc, so it is meant for use on compatible hook-and-loop style backing pads in the 6 inch class. Mirka recommends pairing Microstar with a 5 mm interface pad for the best result. It is also specifically developed for dry sanding only, which is important if you are matching this disc to your process and dust control setup.\u003c\/p\u003e\n      \u003cp\u003eThe Mirka FM-622-2000 Microstar Film Back Grip Disc, 6\" makes the most sense for users doing fine finishing rather than rough shaping. If you work in automotive refinishing, clear-coat correction, marine finishing, composites, or fine wood surface prep, this is the kind of sanding disc that earns its keep by cutting cleanly, loading less, and leaving a finish that is easier to refine in the next step.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eBuilt for Fine Surface Correction\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/20260624466_1.jpg\" alt=\"Mirka FM-622-2000 Microstar Film Back Grip Disc, 6 inch abrasive disc for fine dry sanding and paint rectification on coated surfaces\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis Mirka sanding disc is made for the part of the job where surface quality matters most.
