Cabosil - Fumed Silica Thickener in Quart Tub

Worked great as a rigidizer for ceramic blanket in a forge. Mixed 1:2 with water and a few drops of food coloring. Brushed on. For my blanket feeling like stale pound cake and ready for use.

I bought 2 of the containers for a rebuild of my boats hard top. It was recommended by a guy that does fiberglass work for a living. It works great by just adding some and stirring in until you get the consistency you need. The resin thickened quickly with small amounts added, keeping it from running past the intended work area. I also used a bunch to make a paste for some crack fills and it was excellent. I couldn’t detect any weakness in the filled areas either.

Smaller than expected but good
