Talc, 200 weight polartec undies, and 90 deg Farenheit in the blazing sun does not a slippery arm or neck make.
I learned my lesson this summer when my talc turned gooey on my arms....ended up popping off my right locking ring for my dry gloves.....now imagine 230# of thick necked, bald Irish standing on the shore with my left wrist through the seal, my head through the seal, suit unzipped and struggling to reattach the ring (Mind you, I had to turn my right sleeve inside out...."
I was one sweaty fool by the time I was ready to go.....I ended up having to wipe down my right arm and then talc it from elbow to wrist to keep it dry whilest I pushed it through the wrist seal....I was never so happy to hit the cold water as that day.
I've since changed to an armor all sized bottle - ex hair spray bottle- with shampoo/water solution...a liberal dose on each arm and hand and my thick wrists slide through with the greatest of ease!!!
