Dan - I tried to purchase crystal seal (for some of Stalcup's flies) through Bob Marriots last week since I couldn't find it locally. I e-mailed them first, they in turn contacted Shane directly. It turns out it is no longer made however Shane is recommending ice dub as a substitute. There may be some crystal seal still floating out there somewhere though. Personally I think ice dub is too coarse out of the package.
