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

Great product, excellent service, highly recommended.

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

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.

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.

Works great
