I would suggest the use of talc; or, whatever they're currently using as a substitute -- corn starch -- if that concerns you (just don't huff it), to ease your hands through the wrist and / or neck seals. They can be very easy to tear; and you'll learn that drysuit repairs do not come cheaply . . .
I tried talc, it works if everything is dry, or at least helps. Once its wet that's it. I have read KY Jelly or the equivalent will work better for neoprene seals. I'll give that a shot, but they really need to be stretched some more.
