Permatex 84209 PermaPoxy 4 Minute Multi-Metal Epoxy
The Permatex 84209 PermaPoxy 4 Minute Multi-Metal Epoxy, Two 1 oz. Tubes is a metal glue worth buying because it sets in four minutes. I explained above with the Super Glue epoxy why quick setting metal glues are great. Additionally, this adhesive is resistant to both water and solvents, which is good because it means you can use the glue outside. This glue also has a crazy high tensile strength of 4500 PSI. I touched on above why high tensile strengths are desirable. Like some of the other glues on this list, it can also be drilled, sanded, threaded and filed once dry. As I said above, this is great if you want to do any of these things but don’t want to risk potentially destroying your hardened bond.
