Some great ideas and thanks for all the links too, I ended up getting a pair of Ronstan deckhand gloves. I'll just use them when any blisters are red raw, then when they have dried up and gone to dead skin I'll leave the gloves off or for when ever someone needs a deckhand

I got a few tips from Mike at Onboard too, he said just poor metho over the blisters then after you hit the roof they'll be all dried up.
