Hey guys I have a 6x14 cargo trailer and I have need advice on how to go about adding diamond plate to the bottom exterior. The trailer frame has surface rust and it's reacting with the aluminum siding causing holes in the siding.
My plan is to remove the fenders and maybe the interior walls if I need access to the backside of wall. Cut out 6 inches of the bottom aluminum siding on both sides. Sand and paint the frame to protect the new materials. I would add a piece of flashing to keep everything water proof behind the diamond plate. Im thinking if I use .063 diamond plate screwed to studs every 16" and in the center of the studs. Can I get away with not using a piece of trim on top of the diamond plate?
I see most trailers have a piece of J trim covering the top of the diamond plate. Only reason I don't want to use trim is cost reason's. Im trying to figure out if this trailer is worth building out or should I sell it and find something that needs less work. I built my 6x12 when I was single, now I have a family so I need more room for sleeping.
