If you often find yourself scrambling for convenient and suitable filler, jb weld epoxy putty is your end point. The Weld 8267 SteelStik Steel Reinforced Epoxy Putty is a high quality product. It's a piece of hanging folk art made from purposefully rusted tin, which is then painted, showing 3 pairs of animals. It is like a putty that you squish in your hands to mix the two components before you use. The easy to use is three stars due to it hardening too quickly after mixing, but you will love Epoxy Putty Sticks and use them all the time.

The putty-like adherence then hardens to a steel-like strength. It is easy to work with, strong, and easy to drill, shape or form to suit your needs. The product can be drilled or tapped once it hardens. It is great for use where pouring a liquid epoxy won't work.
