###  Tried with two old bivy sacs. Did NOT work -- at ALL. Flaked off in bigger pieces, even faster than the original. I surmised much as Mara forecast -- the original fabric was not clean enough -- some of the old coating remained after it *appeared* to come off, and would not allow the new polyurethane to seat. RATS.
