Oh bummer. I have the whole raft completed except tiedowns! I’ll have to do what I can through the T-zip.
Looking around now I’m finding a several different versions of SeamGrip.
SeamGrip+SIL (silicone coated fabrics)
SeamGrip +WP (nylon, canvas, vinyl, rubber)
SeamGrip, white & blue tube (coated and uncoated polyurethane)
AuquaSeal+FD (neoprene, nylon, vinyl and rubber)
And a whole bunch of others…
