I saw a guy ( Not going to mention his name) land his plane and half of the 8 rubber bands had broken. So it was held on with 4 rubber bands that were as old and weak as the 4 that had broken. I asked him how old they were and he said that he didn't know. He said they seemed ok when he put them on the wing before the flight. As we sat there we watched another rubber band snap. Now it was just held on with 3, and it was just sitting there.

I don't think I ever saw him use old rubber bands again after that.

So you can store them in corn starch, or wash them with dish washing liquid or put chemicals on them to make them last longer, but you just end up spending more than what new rubber bands cost. It's amazing how much money people will spend trying to save a few cents.
