I stumbled upon a product made by Winzer, which is a company that supplies all kinds of hardware and specialty chemicals to automotive and industrial business. It is a heavy duty synthetic lubricant that also contains Teflon Gel, is completely clear and non-staining, and so far is working fine. It is "ultra sticky" too and smells kind of like a hot crayola...

The name of the product is "Winzer Poly-Lube". It originally is made for industrial chain and sprocket applications, but a chains are chains and teeth are teeth so...
If anyone is interested I can get you some contact information, or I could even sell you a can at my cost plus a buck or two freight if you want to try it...
BTW-I work at a Toyota dealership....
