West System Epoxy Kit, 105 gal, 206 quart Slow Hardener w/ Pumps - Fiberglass Resin

I've only use this a time or two, but the stuff has an excellent hold. I use it to fill voids in wood a lot, but it has other applications as well. If you're filling a gap in a wood piece, mix in some really fine sawdust a slightly darker color than the material you're working with and it will give a nice accent, rather than just a clear filled gap.

A little pricey but excellent product and worth the money. I used it for making a surfboard. It does not eat up the Styrofoam core and provides plenty of working time

This is the good stuff. Easy to mix with the included pumps, no measuring required and worth every penny.

A proven epoxy which, when used with the pump system, is perfect for a wide variety of projects.

It does what I need it to

Consistent quality as always.

Works great

Awesome product
