Sorry for the bump but I gotta ask this. I also have the Permatex Ultra Slick Multipurpose grease. It says directly on the bottle that it is safe on plastic, rubber, metal, wood etc. It also states that it contains petroleum. I believe this stuff is just like Superlube and is based on Synthetic Hydrocarbons. So heres te thing....if it contains petroleum how is it safe on rubber and plastic like it states? Are you using it on your gears as well as piston rings?
