I have my trailer frame built and am now beginning to put up the sides and top. If I use plywood for the top, what kind of epoxy is best to seal the plywood? I know that I will probally paint it with a good exterior paint but I'm not sure what to use to seal it first. As I'm putting the top on can I use a brad gun and glue to apply the plywood to the spars? What is the best type of glue to use?
Thanks
