We have done business with ReVitalized Trailers. Bought our axle through them. Had problems with the axle but it wasn't their fault. They seemed like good folks and were willing to do what it took to get our business. They are a "new" company ~ within the last couple of years. They seem to regularly polish trailers. If you are wondering how well they do, go to their lot and check them out. They seem to be okay. Owned by a young couple and the Grandfather. Spendy, however.
Maybe they will give you names of folks they have polished for and you can contact them for references???
