This is a sanding abrasive designed for preparing repaired areas for primer. Model Number: OS-570-003. If you are trying to standardize your sanding steps and cut down on guesswork in the prep process, this roll is built for exactly that job.\u003c\/p\u003e\n      \u003cp\u003eIn Mirka's OSP sequence, the number 3 step is used to prepare the repaired area for primer by reducing scratches and expanding the featheredge. That matters because the transition area around a repair is where poor prep usually shows up later. Instead of treating this like just another strip of abrasive, Mirka positions it as part of a defined process, so the operator knows where it belongs and what outcome it is supposed to produce.\u003c\/p\u003e\n      \u003cp\u003eThe 2-3\/4 inch by 33.5 foot perforated roll format is practical in a real shop. You can tear off usable lengths as needed, which helps manage material use better than grabbing oversized sheets for small repair zones. The roll format also makes it easier to keep one consistent abrasive on hand for repetitive prep work instead of stocking multiple similar pieces for the same stage.\u003c\/p\u003e\n      \u003cp\u003eMirka also ties this product into a broader dust-free sanding setup. According to the source data, OSP abrasives are meant to be used with Mirka sanding tools, a dust extractor, and the Mirka solution cart as part of a complete sanding system. For collision repair shops and paint departments, that kind of system approach matters because it helps keep process steps consistent between technicians and from job to job.\u003c\/p\u003e\n      \u003cp\u003eWho is this for? Body shops, refinish techs, and anyone handling automotive primer prep who wants a more repeatable workflow. If you already run Mirka sanding equipment, the Mirka OS-570-003 OSP-3 Primer Filler Perf-Roll makes the most sense because it drops straight into that process. If you are just looking for a random general-purpose abrasive, this is more specialized than you need. If you want an abrasive built around the primer-prep stage, this is the right lane.\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 Consistent Repair Prep\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\/20260623836_1.jpg\" alt=\"Mirka OS-570-003 OSP-3 Primer Filler Perf-Roll abrasive disc surface for automotive primer prep and body repair sanding\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis Mirka abrasive is part of a defined sanding sequence, which is the big advantage here.
