Earthlings, At least I got your attention. he he. I have tried it on the car headlight lenses. (Only one lens that is, because that way I can have a "controlled experiment", right? ) I have also put it on a Mustang like "Brumby" collects. I also drank some but I would not recommend that, even though Blue says he takes it. (Drinking it reminded me of when we were little boys, we heard stories of children having to take castor oil!) Who said "Oils aint oils sol" Oh that was another oil sorry. Anyway, the plastic looks great.
