Where did you purchase the Cab-o-Sil? Directly from Cabot?

Try these guys - they sell hydrophobic Aerosil - Cab-o-sil's competitor
(maybe the originators?). It's very cool stuff - definitely want to use
gloves when handling large quantities - it waterproofed my hands. When my
order came in I tested it by brushing some into a beadhead nymph (size 14
teeko bug) and the damned thing floated all day. When I submerged it, it
had the coolest air bubble around the fly.
