I have been working on a permanent outdoor theater solution and need some knowledge/tips to do it right. I have been using a framed blackout cloth on eye bolts to bring out when we are watching movies. I am doing away with this and building a permanent screen made of plywood. This screen will be 200 inches. I have a couple questions I need help on understanding.
What type of plywood can I use outside all the time? I looked at birch plywood for the smooth finish, I don’t want knots (was going to seal)
What is the best way to hide the seams in butting up the pieces of plywood? I have seen videos of people using bondo or do I just use wood filler?
What type of paint? I had planned on priming it with an oil based Kilz, then using a flat white. I read on the forums of people using pearl or metallic paints, but are any of these rated for outdoor use?
Vision of what I am aiming for:
Currently I have a computer in my garage. I punched through the back and buried 2” PVC out 30ft. This enters into a 4” container buried at ground level. I have power and video ran though the PVC and can now just store my cables in this container. My goal is to just be able to bring the projector out and plug it in, minimal setup and take down for the location of this viewing area.
Picture of current screen, that will be replaced with 200" that utilizes most of garage wall:
4" Container to store cables:
PVC cap placed in 10" Valve Box (hidden under rock):

So right now the last piece of the puzzle is creating the screen. I am open to suggestions as I am trying to do this right. Thanks in advance for any input.
