Wish i could give this 11 stars, great epoxy thickener. Adds lots of structure and great price. Unless you are trying to 16ft boat worth of thick viscous paste, you'll never need more than a quart

Good stuff, as expected.

Works great to thicken epoxy resin without reducing it's strength significantly.

This stuff works great for thickening gel coat or fiberglass to make it more like filler consistency.
