The Best Glues for Plastic of 2023

The J-B Weld waterproof glue for plastic can was designed for repairing boats, fixing dock pieces, or fastening metal hardware at the marina. Among the best adhesive for plastic and metal, it is heat resistant up to 550 degrees Fahrenheit and has a tensile strength of 5,020 PSI, which means that it would require 5,020 pounds of force to pull apart two objects fastened using this glue. It can be used with aluminum, fiberglass, metal, plastic, composite, and wood. It's a two-tube epoxy that comes ready to mix at a ratio of 1:1.

The epoxy takes between four to six hours to set. This gives you a long period of adjustment, to ensure that the adhesive and materials are set just right, but it's best to clamp pieces in place once you have a perfect position. The complete cure time is between 16-24 hours, and once cured, it can be tapped, filed, sanded, molded, and drilled.
