To clarify: KY will help reduce friction between bungees when installing. Also allows them "equalize" and find their "home"
a little better. Water based, so, will not affect rubber.
watered down, is not as messy to deal with, mist the area with a spray bottle if things start to dry out.
Toughest part will be finding someone to purchase the KY for you.
good luck, be careful.
That was gonna be my suggestion.If that doesn't work, they're going back to Univaire.
