Sorry if this is the wrong group to ask this question. I am putting in a home theater in my basement. I purchased a DLP projector. Rather than go with a premade screen ($$$), an alternative is to make my own. They make a paint called GOO Screen. It is acrylic paint. The screen will be 60″x80″ or a 100″ diagonal.  My questions is what material could be painted and not bleed imperfections through? I don’t want a seam so I’ll need to get 5′ x 8′ material. I can get material in 5×8 sheets at my local lumber supplier. They have a material called double refined MDF. Never heard of it, but thought it might do the trick. I also considered HPL. I just don’t know if Acrylic would work. It requires two coats of a base coat, and two coats of top coat. What would you recommend to give me the smoothest surface to apply the material? The acrylic takes a full six weeks to fully harden (per an instructional video at the web site).  Anybody here use this stuff? Any comments appreciated. Thanks.

JessEm Wood Sabre

The beam has deep detents that index the fence precisely at 1/2-in. increments, and there’s a well-machined and easy-to-read micrometer adjustment that will set the gauge to any distance between the indexed points. However, the detents are so positive that they sometimes interfere, drawing the fence toward them.
