Armor . . . Your comments got me thinkin' (doesn't happen very often!) so I went into the tool box and found an old bottle. It is called "Armor" and it "forms a barrier against oils", according to the bumpf on the package. I was able to find it for sale in a few places on-line but it looks like it is hard to find these days. Also found a useful thread on another forum with several first hand experiences. Here it is: http://www.ultrunr.com/p-oak.html
Discontinued . . . Wellll, shows you what you get when you start thinkin' . . . I went back and looked on the Tec Labs site and couldn't find Armor. So I called and sure enough, as hoovermd thought, the product has been discontinued. Oh well!
