I bought some DIY stuff and did a small yard trailer. There was a lot of prep work. Sand paint real good, leave nothing shinning, clean real good, twice or three times with non oil base residue cleaner like alcohol. Brush on product at all corners and anywhere a roller can't get to. Then roll on main area first one way then cross hatch the other way. So far this has held up real good. I haul wood, leaves, dirt etc. Have had very minor peeling.
