Built around a self-sharpening aluminum oxide mineral coating, the sponge resists clogging and maintains cutting performance throughout its work life. At 1 inch x 2.625 inches, it fits comfortably in the hand for controlled, consistent pressure. The sponge ships ready to use with no prep required. Automotive body technicians and refinishing professionals reach for this sponge when shaping glaze, spot putty, or primer during the finish preparation stages of a body repair job.\u003c\/p\u003e\n\u003cp\u003eThis sponge is specifically suited for Stage 3 and Stage 4 work in automotive body repair sequences. In Stage 3, it shapes and sands glaze or spot putty prior to primer application. In Stage 4, it sands applied primer before a finer grit, such as 400, is used to refine scratch patterns ahead of topcoat. The compact block format makes it easy to work curved panels, door edges, and confined repair areas where a flat sheet or block sander is impractical. Sold individually, with a minimum order quantity of 12 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320-grit aluminum oxide mineral coating for consistent material removal on glaze, spot putty, and primer\u003c\/li\u003e\n  \u003cli\u003eSelf-sharpening mineral structure extends sponge work life and reduces clogging\u003c\/li\u003e\n  \u003cli\u003eCompact 1 inch x 2.625 inch block fits curved panels and tight repair areas\u003c\/li\u003e\n  \u003cli\u003eReady to use straight out of packaging — no soaking or prep needed\u003c\/li\u003e\n  \u003cli\u003eDesigned for hand sanding, allowing direct tactile feedback on surface contour\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Stage 3 and Stage 4 of the 3M Body Repair System for automotive refinishing.

Sand the repair area with this 320-grit sponge before applying primer, then use it again on cured primer prior to refining with 400-grit. Apply consistent, even hand pressure to avoid creating low spots in the repair area. Follow primer manufacturer recommendations for cure time before sanding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 1 inch x 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051131030701\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010300638\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346421350706,"sku":"7010300638","price":113.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310531119.jpg?v=1782079750","url":"https:\/\/voomisupply.com\/products\/3m-7010300638-performance-sanding-sponge-320-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
