WEST System Epoxy cures to a high-strength plastic solid at room temperatures, by mixing specific proportions of liquid epoxy resin and hardener.
This clear, pale yellow, low-viscosity liquid epoxy resin is formulated for use with WEST SYSTEM hardeners. It can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance.
Designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals, 105 is an excellent adhesive that will bridge gaps and fill voids when modified with WEST SYSTEM fillers. It can be sanded and shaped when cured. In roller applications, it has excellent thin-film characteristics to flow out and self-level without fisheyeing. 105 resin has a relatively high flash point and no strong solvent odor, making it safer to work with than polyesters.

If the pump kit would screw in place on the container it would have been the perfect deal. Pump kit was for a smaller container obviously.

The setting time for this epoxy works well for my woodworking projects. Have tried a couple others with longer set times that result in failures.

I Run a furniture repair/refinish shop and have used this epoxy to fix things that no other glue can do. I trust it to do what I need it to do.

I used this product to apply Kevlar skid plates to 2 Royalex canoes, bow and stern. I just followed the instructions and it was pretty simple to do. It washed off my hands fairly well with Dawn detergent.
