This is a \u003cstrong\u003e6 inch sanding disc\u003c\/strong\u003e designed for \u003cstrong\u003efine surface prep and finish sanding on automotive coatings and refinishing materials\u003c\/strong\u003e. If you are working in collision repair, automotive OEM production, or any shop where surface quality matters, this disc is built to keep the scratch pattern even while staying easy to control by hand or on a machine.\u003c\/p\u003e\n      \u003cp\u003eWhat makes this disc different from a standard paper-backed abrasive is the three-part construction. Mirka pairs durable aluminum oxide abrasive grains with a flexible foam base and a grip backing. On the job, that matters because the disc can follow body lines, compound curves, and subtle panel shapes more naturally than a stiffer abrasive. Instead of sanding only the high spots, it stays planted better across the surface, which helps reduce uneven sanding marks on clear coat, primer, gel coat, paint, and other refinishing layers.\u003c\/p\u003e\n      \u003cp\u003eThe grit on this version is \u003cstrong\u003e400\u003c\/strong\u003e, which puts it in a useful range for controlled dry sanding where you want refinement without jumping straight to ultra-fine finishing. That makes it a good fit for technicians stepping through a paint correction or surface prep process and wanting a disc that cuts cleanly without getting overly aggressive. Mirka also offers this Iridium Soft line in a broad grit range, but this specific model is the 400-grit version tied to SKU 24-6MF-400.\u003c\/p\u003e\n      \u003cp\u003eMirka's \u003cstrong\u003eMultifit\u003c\/strong\u003e hole pattern is another practical advantage. The hole layout is built to support efficient dust extraction, which helps reduce clogging, pilling, and swirl marks during sanding. In real use, cleaner extraction means the abrasive keeps working longer and the work area stays easier to manage. That is especially important in finish sanding, where trapped dust can drag across the surface and cost you extra cleanup or rework.\u003c\/p\u003e\n      \u003cp\u003eBecause this is a \u003cstrong\u003egrip-backed 6 inch sanding disc\u003c\/strong\u003e, it is meant for use with compatible 6 inch hook-and-loop style sanding pads in manual and machine sanding setups. The disc is also built specifically for dry sanding, not wet sanding, so it fits workflows where dust extraction is part of the sanding process. Shops already set up around Mirka-style dust-managed sanding will get the most out of the Multifit pattern and the foam-backed design.\u003c\/p\u003e\n      \u003cp\u003eAs for who should buy it, this product makes the most sense for automotive refinish techs, body shop pros, paint correction specialists, and serious users who care about surface quality on curved panels and coated parts. If your work involves primers, clear coats, high-gloss polyester surfaces, gel coat, or waterbased primer, this disc is aimed right at that kind of finish-sensitive sanding. It is not the disc you grab for rough stock removal. It is the one you reach for when the surface is already close and the next step needs to be clean, consistent, and predictable.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eBuilt to Follow Body Lines\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\/20260623799_5.jpg\" alt=\"Mirka Iridium Soft 6 Inch Grip Multifit Discs package and discs for automotive finish sanding and curved panel surface prep\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eFine finishing gets harder when a stiff disc wants to flatten everything it touches.
