I’ve spent the day completely stripping my ‘tip-run’ trailer back to the chassis, wire-brush, prime etc. I’ll rebuild the floor and sides with marine ply but it occurs to me that something with a laminate/acrylic kind of top would make for a much easier life/durability but apart from actually putting a separate top sheet of acrylic on top of the ply I’m stumped for ideas - anyone ever come across a material (marine ply / OSB style etc) that’s still in 8x4 sheets but has a plastic/acrylic type top??
