ok, not trying to be mean or anything, and definatly dry is the way to go if you ask me, but maybe a class is in order for learning how to use the drysuit. I mean that's a big thing-knowing how to use the dumps on accent or if the inflator gets stuck.
How mine work is I can turn it so that it's all the way open-meaning any squeeze pushes the air out the vent. I can then turn the valve so that it takes more squeeze to push air out. Keeps turning till it stops turning, and it's cracked down all the way. Then I actually have to push on the valve - like purging the reg-to manually vent air. It's that simple, but practice it and have someone at least show you the vent/unhook/roll manuver.
The wax can be found in almost any lds. It looks like the glue for a hot glue gun or a big clear crayon.
