Oh, another thing I should have mentioned, is a very cool product we have been playing with, Melco Tape.
This is a three layer iron-on tape, with an outer layer of stretchy nylon, which can be used to reinforce seams or patch rips in the nylon layer of neoprene wet and drysuits. Since it stretches just like the base material, it doesn't peel off when the base material is stretched, the way most other glued-on tapes tend to.
It's useful as a subsitute for sewing on home made neoprene projects, as well as for patching rips in the nylon layer on neoprene suits. Or pinning down the loose ends so a whole seam won't unravel when the stitching has become damaged, or when a neoprene drysuit seal has been trimmed.
Only problem is the distributor, McNett (the Aquaseal people) only sell it to OEMs in huge roles. Wilderness Fabrics sells the 3/4" tape in small quantities, and McNett retail packages it in 12"x3" pieces as Iron Grip. Sweet is also considering carrying the stuff.
