Zip poles work great for temp walls, a lot of my contractors use them with either drop cloths or plastic. Where are you going to set up the exhaust? The most effective way would be to close off the ceiling to create negative pressure. I played around with mine a few times before going to Depot and getting a 20' x 100' of 6 mil and covering the entire area with one piece to avoid air leaks. Is the boat backed in with bow towards the garage door? I am going to the shop tonight and will take a vid of my set up, I can help you so that you would have zero dust or smell in your garage and no glass dust clouds while your working. I only live 25 min from you and would even give you the remainder roll to do it, looks like we're both at the same stage of the project, I only have a day left of the grind. It's all about setting up your negative & positive air.
