I would say, it depends on what you want. I had a 1966
Safari polished this past spring by P&S. They did a great job. I found they take it to a point, but not the "mirror" finish. But, they have the most "consistent" finish. You will find "NO" area's that have a slightly different look. When you try to go to the "mirror" look, most of the time you, may have areas that have a slightly different look or almost feel. I had someone that also polishes trailers look at mine after the job was finished. He ask "How did they get it to be so consistent?" I called Steve and asked, he told me "It's 25 years experience". I would say the P&S job would look more like it did from the factory than the mirror look. I think some people do to Airstreams like some people do to old cars, they "over" restore them. I've see better paint jobs on some cars than the factory ever could have done.
