Ever noticed that the plastic bottles some peanut butter comes in get really waxy and sticky on the outside over time? It must have something to do with the peanut butter oil and its reaction with the plastic - the plastic must be absorbing it. Even happens when the peanut butter is in the refrigirator.
So I don't doubt it works. Maybe even just pure peanut oil works. Interesting....
Hey, we could manufactur a "patented compount" that restores all of your under the hood rubber, and really just be selling peanut buttern in an aerosol can! :p
