I flew some contest rubber power back in high school. The very best stuff
for lube was a Dow product which was hard to find and whose number I can't
recall. I personally used a product called Syl-Glide which used to be
available from Pep Boys.
Armor All didn't work so well; STP Son-of-a-Gun lotion was much better.
Almost nobody used glycerin and soap.
Why on earth were you trying to lube a high-start? It doesn't give you
any more stretch. The lube does just what it's designed to. When the
motor is wound, the separate strands chafe against each other. Without
lube, it'll start eating itself after four or five runs.
For non-winding stuff, like catapults, high starts, etc., your best bet is
to wash after each day's use, dry, and dust with talcum powder. This goes
for latex tubing too.
And store everything in the DARK! UV radiation does a number on it.
