It seems a lot like bar oil honestly...just from a fingertip rub it around and then wipe it off analysis...
I actually didn't use any service. I was browsing the big internet sites for weeks. I saw that some of the big dealers had some nice used trucks in my price range and milage. The day I got her I just happened to be in that area, and it's the same dealership that the company i work for gets our snowplow fleet trucks from. I pulled into the used lot, drove through, and I swear she was looking at me from the last spot in the lot, in the back. Salesman says they usually don't keep and sell anything older than 5 years, but this one was too nice and clean to send to auction.
