Use an exterior grade plywood fill any voids in the edges before painting. I think the reason it bent forward is you have a tall piece without any reinforcement. To stop the bow reinforce the back edge with another piece about an 1 1/2 wide.

I think Marine Grade plywood is what you want. If you can make a boat out of it is should hold up to a little rain.

AGREED …..... just fill edges with bondo ….....or could use 2X4 treated for reinforcement

Nice work. Like others mentioned it needs a stiffener board on the back to make it more rigid. Even if you used 3/4 marine plywood it would bow without additional support.

MDO is made for outdoor painted signs, kind of just what the doctor ordered. Just don’t confuse it with MDF! Even better, because of the layer of whatever that stuff is on the surface, it’s really smooth and takes paint well.
