Quick question. I own a 1993 Champion with a single axle trailer. The trailer is in fairly good shape except for some significant rusting on and around the bunk brackets where they are welded to the trailer. I would like to fix or repair these areas before spring season gets here. I have never done any cosmetic work like this and was wondering if it it something I can do myself, or should this be left to a professional. I probably will be replacing the bunks as well; I have a friend who did his years ago and has some experience there. I'm more concerned with the integrity of the welded brackets to the trailer itself. Any advice ?? Thanks a bunch.
