PSA Linkrol Disc, 320-Grit, C-Weight Backing is a pressure-sensitive adhesive sanding disc made for fine surface prep and finish sanding. This is an adhesive sanding disc designed for dry sanding primer, lacquer, and similar coated surfaces. Model Number 23-342-320. It is a practical choice for body shop work, paint prep, woodworking finish sanding, and any job where you need a clean, controlled scratch pattern instead of aggressive stock removal.\u003c\/p\u003e\n      \u003cp\u003eThe big story here is the 320-grit cut paired with Mirka's Gold abrasive design. At this grit level, you're not trying to hog material off fast. You're refining the surface, knocking down minor imperfections, and getting coatings ready for the next step. That makes this disc a better fit for finish-stage sanding than for stripping or heavy shaping.\u003c\/p\u003e\n      \u003cp\u003eMirka also builds this disc to stay productive at higher sanding speeds. The semi-open grit binding and special stearate coating are there for a reason: they help reduce clogging and pill forming, which is exactly what slows finish sanding down and ruins consistency. When the abrasive stays cleaner, you get a more even result and better life out of each disc.\u003c\/p\u003e\n      \u003cp\u003eThe 6 inch size fits common sanding setups that use PSA-backed discs, and the C-weight backing gives the abrasive enough body for controlled sanding without turning it into a heavy, overly stiff disc. For jobs involving primer and lacquer, that balance matters. You want the disc to track well, keep contact with the surface, and leave a finish you can build on.\u003c\/p\u003e\n      \u003cp\u003eIn real shop use, this is an all-around sanding material meant for a lot of day-to-day prep work. Mirka positions the Gold line as a durable option for many sanding tasks, and the 23-342-320 leans toward the finer end of that range. If you're moving through finishing stages and need a disc that can handle dry sanding cleanly, this one makes sense.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? Painters, auto body techs, woodworkers, cabinet installers, and serious DIY users doing finish prep will get the most out of it. If your work involves primer, lacquer, or other coated surfaces and you want a fine abrasive disc that holds up well and resists loading, this Mirka sanding disc is aimed right at that job.\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 Cleaner Finish Sanding\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\/20260624319_1.jpg\" alt=\"Mirka 23 Series Gold 6 in.
