I wouldn't recommend using the Krazy glue, unless you wanna risk it getting into your blood stream. There are better alternatives to use. The liquid bandage was already mentioned, as well as the tuffskin. If you do use the tuffskin, I'd avoid spraying it directly into the open wound. What I've done is spray a q-tip with the tuffskin and wipe the area around the wound and then apply the bandage, wrap, tape, etc.
You may also want to look into a product i believe is called NewSkin. It is like a thin layer of material that resembles skin so that it covers and cushions the area.
Lately at my Athletic Training internship, with all the new incoming freshman football players, we've had a lot of torn up hands due to them not being accustomed to the workouts. So we've just been keeping the area clean, putting some telfa pads or gauze over the area, then wrap it with PowerFlex and one strip of athletic tape. Seems to work really well with them.
Hope this helps.
