yeah, i play a coupla hours a day, and i have not allowed my left hand's calouses to get wet in the shower since after a gig in which i used superglue on my calouses, it worked pretty well, cause my calouses were all but gone from overplaying them for a few days, but i needed to get the superglue off. try superglue, but DON'T USE TOO MUCH i did, and it was a mistake, i couldn't feel my finger, and i freaked out the first time i used it :)
