I don't salt them and had a time getting a skin to stick that a friend gave me that had been salted.
I ended up taking the skin off the bow and washing it for about 1/2 hour before I could get the glue to stick on the bow.
I don't wrap my skins with an an ace bandage or gauze while they dry either, waste of time in my opinion because you only put pressure on the sides, not the back.
I spend about 20 minutes a skin pushing it down with my thumbs and working all the excess glue out to the sides and positioning the pattern as perfectly centered as I can.
By the time I have all the excess glue worked out the skin is stuck, partially dry and isn't going anywhere, no need to wrap.
