I am astounded at how well it worked. the wintergreen is supposed to have a natural plastisizer in it called meythyl salicylate. the test bits did not swell up noticeably and are still pliable after a couple days sitting on the bench. I put another set in mix yesterday & they show improvement, but not as dramatic as the first set. I intend to leave them in until tomorrow & see if they continue to improve. It's the same mix though, so maybe some fresh materials would speed things up.

I got the oil from a local health food store, another source is homeopathic medicine. I hear that sports medicine uses it too.
It would be a really great tip if the results last. We can often restore the looks of rubber but then it goes back to it's aged appearance after a month. The treatment is needed again. Please report if your method seems to have longer lasting results.

Terrific tip if it stays soft.
