ALso being a cheap--- , frugal person, I treated my 2 x6 trailer deck with used motor oil.
OK i can hear some laughter...So when I backed my sand rail up on the trailer with the 1966 VW motor pulling the front wheels up the ramps, the tires spun and the sand rail went sideways toward the edge ...OMG.
IT was close...I am going to treat the boards with some traction paint and maybe a low guard rail along the edge,
