Hey all, just picked up a vintage NRS microcat cataraft for free!! —but both cones on one of the tubes are busted open. We called NRS and we can’t get official replacement because it’s so old—probably 25 years or more old— and a new tube is too expensive. Anyone have any advice for how to repair or replace these old cones? I am pretty sure these are hypalon. The other tube is in good shape. Both of these cones are ripped at the seam and also a little ripped up through the cone itself. Thanks for any help!
