I am facing the same dilemma, i have a 2000 Haulmark 20 ft. its been a great trailer and is in good shape however the paint is faded, I tried the Rustoleam color back it helped a little but the trailer still doesn't look good. I talked to Haulmark and they don't do reskins and the new panels are around $90 a piece. I saw an ad for a paint shop here in N.J. that paints trailers I might call for an estimate. My roof was getting spots of surface rust, I sprayed Silver Rustoleam on a few of the spots but recently bought a few quarts of Silver Rustoleam and took a roller and did the whole roof, it came out great.
