Our 3M™ panel bonding adhesive is a cost effective two part epoxy adhesive for bonding replacement body panels. From its fast, convenient cartridge system the adhesive seals and bonds steel, aluminum, SMC and FRP securely in a single operation. The result of years of development and testing, our 3M™ panel bonding adhesive bonds and seals plastic and metal substrates including cold roll steel, aluminum, SMC and FRP (traditional fiberglass). It is ideal for bonding quarter panels, roofs skins, box sides, van sides, utility vehicle sides and door skins - anywhere that requires a lasting bond for outer body panels - as specified by OEM. Many interior or other adjacent parts that must be removed to avoid damage from welding can remain installed when bonding.
