It comes pre-mixed with chopped fiberglass to provide additional tensile strength and impact resistance, and is supplied with a white cream hardener for reliable curing. Use it to restore corroded panels, rebuild edges, or cover holes when welding isn’t practical; it bonds to metal, wood, and fiberglass and resists water and rust once cured.\u003c\/p\u003e\n\n\u003ch3\u003eHow does DURAGLASS differ from standard body fillers?\u003c\/h3\u003e\n\u003cp\u003eDURAGLASS incorporates chopped fiberglass strands inside a polyester resin matrix, creating a composite repair that withstands stress and flex better than plain fillers.

DURAGLASS is aimed at professional body shops, restorers, and experienced DIYers who need a strong, water-resistant filler for medium to large repairs. If you require faster, reinforced rebuilding without the time and equipment for metal fabrication, this product offers a durable alternative. It’s not a substitute for full structural metalwork on critical safety components, but it excels at reinforcing panels, filling holes, and providing a reliable base for sanding and topcoat. Always follow safety guidelines and ventilation recommendations when working with polyester resins and hardeners.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can DURAGLASS be used on rusty metal?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—remove loose rust and scale first; adhere to clean metal for best bonding and long-term results.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need fiberglass cloth with DURAGLASS?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Fiberglass cloth is optional: use it for bridging large holes to add bulk and extra reinforcement.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"U.S. Chemical \u0026 Plastics","offers":[{"title":"Default Title","offer_id":48084010533022,"sku":"B0082LF7B6","price":64.73,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/us-chemical-plastics-duraglass-front-packaging.jpg?v=1785843331","url":"https:\/\/northtrailauto.ca\/products\/u-s-chemical-plastics-duraglass-reinforced-body-filler-25-6-u-s-fl-oz-pre-mixed-chopped-fiberglass-high-strength-rust-resis","provider":"North Trail Auto","version":"1.0","type":"link"}
