## Overview

J-B Weld Original Steel Reinforced Epoxy Syringe is a high-strength, two-part epoxy adhesive that creates a permanent bond with a tensile strength of 5020 PSI. It sets in 4-6 hours and fully cures in 15 hours, turning dark gray upon hardening. Resistant to temperatures up to 800°F, it can be molded, sanded, drilled, and filed, making it ideal for metal and multi-surface repairs in automotive, plumbing, marine, and home applications.

## Description

J-B Weld is the original ColdWeld 2-part epoxy system that provides a strong, long-lasting repair to metal and multiple surfaces. Mixing at a 1:1 ratio creates permanent bonding and can be molded, tapped, filed, sanded, and drilled after hardening. At room temperature, J-B Weld turns dark gray in 4-6 hours. Completely cures in 15 hours. J-B Weld has a tensile strength of 5020 PSI and is set to hardbond overnight. When fully cured, it can withstand temperatures up to 800 degrees Fahrenheit.

Review: Always been a fan of J-B Weld. Others seem just as good most of the time, but have stuck with what I know. I like the syringe applicator and much less messy than the squeeze tubes. If mixed good and surface prepared and cleaned this always seems to hold and work long term. Easy to use and durable. For the money it isn't the cheapest, but you always know what you are getting.
Review: I have not use it or open it yet as I am keeping it for future use. I have recently used JB weld waterweld for my leaking fuel tank earlier and I like so much that I have just spent quite a bit of money and ordered a range of other JB weld products. Hope these items remains soft and pliable for long storage. Buy the 2-pack to save money. Thank you very much.
