I just found that I have the same thing going on my Bare drysuit neck seal. The seal as a whole looks great, but I have two points of deteroriation where holes have formed, and one of the holes is surrounded by sticky residue. I have a big trip to California in about two weeks, where I'll be diving on two weekends. I think I'm going to try the bicycle innertube patch procedure to try and sneak by, and then send the suit in after my trip. If things go to hell, I know that I can rent a suit.
Drysuits: the most amazing invention when they work, the most amazingly frustrating when they don't!
