Short glass fiber strands distributed throughout the filler matrix bridge across seams, repair holes, and rust-out areas, providing load-bearing fill that resists cracking under flex, vibration, and thermal cycling — where standard filler would crack and fail over time.\u003c\/p\u003e\n\n\u003cp\u003eApply over bare metal, galvanized steel, aluminum, and properly prepared fiberglass substrates. Short Strand Reinforced Filler is specified for collision repairs involving holes, torn metal, and areas where the substrate continuity has been compromised and requires structural bridging to restore rigidity. After cure, sands and featheredges like standard body filler — no special finishing required. Includes hardener.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Fiberglass Short-Strand Reinforced Body Filler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1 Gallon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrates:\u003c\/strong\u003e Steel, aluminum, galvanized, fiberglass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardener:\u003c\/strong\u003e Included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSand With:\u003c\/strong\u003e P80–P150 grit after cure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Holes, torn metal, rust-out repairs, structural fill\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 01160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51530873733416,"sku":"3M-01160","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0866\/8358\/2760\/files\/3m_01160.webp?v=1773288156","url":"https:\/\/refinishgo.com\/products\/3m-01160-short-strand-reinforced-filler-1-gallon","provider":"Refinish Distributors","version":"1.0","type":"link"}
