I picked up a tip from one of Ted Nugent's
posts on his gear that has worked great
for me.

Serve the area that the release hooks onto
with two laters of dental floss and tie it
off tight. Then clip the ends about 1/2"
long. Burn the ends carefully with a lighter
and extinguish them right when they burn down
to the knot with a wet finger tip. If you do
this right the nylon floss melts and locks the
knot down tight.

You can get a lot of shots before you have to
replace it. Keep the area waxed with silicone
bowstring wax and it will last even longer.
