It's stored outside in the rain, so I thought I needed 3/4" marine plywood. But it appears that ordinary outdoor CDX has the same glue??? And both would need to be painted.
Local bigbox store has some pressure treated plywood. I don't know how to describe it, but on edge it looks like it's already delaminating. And I read that it's caustic to the metal in the trailer. Any experience/recommendations on whether to use that stuff?
What's the best bang for the buck in trailer flooring for outside storage?
