Tip from carpenters and construction workers: SuperGlue bonds to skin very well and this is now used in surgery and sealing cuts. Just push the cut edges together and a little CA on the cut will seal it against air and dirt. The water vapor in your breath will cure the CA in a few minutes. Pat to remove any liquid CA. It will fall off in 4-7 days. DO NOT USE ACCELERATOR!!! (Unless you are a masochist!)
