Hey everyone, i just joined this thread. I'm from michigan and love it. I was searching on the net for ideas for painting plywood for exterior uses. I did like the comments i read. The blog was about OSB plywood. I read that people here used kilz oil base primer, and they said that OSB plywood is weak. I don't agree. I use those nails with washers that are usually used for securing styrofoam to walls, and i use a lot of construction adhesive.
