Went and picked some up at Schucks yesterday. Tried it on Screamin' and was un-impressed last night. It leaves a hazey residue even after buffing by hand and with a 10" orbital. I'll stick with Meguiars or original Turtle Wax. I am gonna try it on the wife's Focus and Mom's explorer to see how it does there. Can't return it so I'll use it up on the Ferds
I do like the micro-fiber polishing rag that it comes with though, as far as silicone, it doesn't say it states that it is synthetic and contains petroleum distillates.
