I have a DIY screen that I have been content with for a few months. Its just a white vinyl insulation strip that gives me a 108" screen when paired with my projector. I've loved it but its not DoAble board, I've heard people talk about that on other websites so it has a small problem. When I am watching a movie just off center there is a little bit of hotspotting. I have been trying to ignore it but lately it has been really annoying to me. Would buying Screen Goo or any other projector paint take care of this? I love everything else about my screen, just annoyed with the hotspotting.
