Well I try to keep up with my cars looks no matter what they are used for. I might get as involved as some do, but I still like to have some sort of shine on my cars. i found and have used some of the products from this guy.

He belongs to a lincoln site that I post on and has always had great information on detailing. He is in NY, but shipping on his products to the west coast are not all that bad. I have seen his Mark VIII in person and I have to say that it looks better than any new car I have seen on the showroom floor.
