Loctite Epoxy Weld Bonding Compound is the best epoxy adhesive for metals like aluminum, steel, copper, bronze, and iron. It embeds bolts and screws into metal, is impact resistant, and is not affected by chemicals like gasoline, diesel fuel, motor oil, transmission fluid, hydraulic fluid and antifreeze.Epoxy and tape are two common no-weld hole repair options. These do-it-yourself approaches are effective when repairing a small hole rather than a significant tear. Specialty epoxy and tape products are designed to patch steel and metal.
