.Loctite Ultra Gel is essential for any survivalist or field worker. Not only is the product great for emergency appliance repairs, but it can also be used for other purposes such as sealing small wounds and creating a protective barrier for cracked toenails (prevents the crack from catching your socks and then tearing or shearing). Be prepared to wait about 30 minutes for the gel to dry before covering a wound or tear. See for yourself: the basic composition was used in Vietnam.
