Guys I?ve done a little reading about using MDO in this forum and would like to use it on our 30? Reinell to strengthen up our stringers. What I would like to know is if I?m doubling up two ?? pieces of MDO G2S do I need to sand off the paper surface on both pieces or can I just glue the two pieces together without prepping the existing surfaces of the MDO plywood?
