Comments about System Three Silica Cab-o-sil Thickener:
I purchased this product to thicken epoxy for gluing wood together. I am building a Guideboat and many joints are vertical, this product does well to thicken the epoxy and keep it from running. It is very light and fluffy, so when scooping it out of the container it is likely you will loose some as it 'poofs' out.
