hand made projector screen grey paint HD

Home Innovation just this at home, buy some paint grey mixed with metallic or silver add some light blue a few drops of black to darken the grey and there you go. Paint cost $40 and screw is blacktout cloth stapled on wooden frame also cost $40. So for $80 my HOME INNOVATION SCREEN was made. No 5 years of research just 5 hours during weekend. No $800 per can as offered by this guy. Just PAINT ITYOURSELF
