Outdoor materials advice

I need to make something akin to this for a sculpture garden for 2-3 years. 84”x42”x3” double sided. This one was made for inside and is Masonite. Obviously that can’t go outside. If I was to make this from a sheet material such as OSB, is there really no way to weatherproof seal it? I have no preference for material other than cost. Milled aluminum would be a dream but not on my budget. I’ve read conflicting info on products such as flex seal, epoxy, polyurethanes etc. submitted by /u/Eye_Worm [link] [comments]
