Hi, I'm new to all this projection screen subject. I have a 1700L 2000:1 DLP projector and I would like to make my own screen. What do you think of MDF and also, I live in Australia so does anyone know the icestorm equivalent here? If not, could someone please post a shade of icestorm 5 and 6 to this thread so that I can get it color matched. what color screen is best for a DLP projector? Does MDF warp after being painted and should I put a primer on the MDF before the final coats? Please Help... Thank you.
