Gray Ultra Fine grade is used for final scuffing of sealers and light surface prep immediately before clearcoat application — minimal scratch depth while still promoting adhesion.\u003c\/p\u003e\n\n\u003cp\u003eNon-woven construction conforms to curved panels and body lines that conventional sandpaper bridges over, ensuring complete, consistent scuff coverage. Unlike sandpaper, Scotch-Brite pads don't load rapidly and continue cutting through contamination and surface oxidation throughout the pad's life. Roll format allows cutting to any length for custom-sized pieces — ideal for large-area scuffing and production-line applications.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Grade:\u003c\/strong\u003e  — Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Non-Woven Synthetic Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 8 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Pre-clearcoat surface conditioning, sealer scuffing\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 07521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51530861969704,"sku":"3M-07521","price":67.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0866\/8358\/2760\/files\/3m07521.jpg?v=1773288027","url":"https:\/\/refinishgo.com\/products\/3m-07521-scotch-brite%e2%84%a2-multi-flex-abrasive-sheet-roll-very-fine-8-in-x-4-in","provider":"Refinish Distributors","version":"1.0","type":"link"}
