The Kraken:Note: I am a very, very new dry suit diver!
Having said that, I prefer the pool hall talc.
I'm just not too keen on running my hands down the inside of my dry suit with K-Y Jelly all over them!
Eeeeeewwwwwww . . .
the K
All you need is a little on your finger, then run it around the inside of the seal. It doesn't take much, and you don't need it all over your hands.
When it's hot (and I'm sweaty) I'll use the KY, when it's cooler I use the talc.
I also powder the seals when my suit is hanging for a while.
