So I recently figured out the enamel paint that PC lists as the "best" choice for painting your own screen is definitely a bad choice. The glare is way too much, and I think I would do better with a tinted grey screen, even though the screen is in the basement.
Here was the article
, and the paint that I used was ProClassic Smooth Enamel Satin by sherwin williams.
Here is a pic of the room:
The walls are pretty dark, so not much light is reflected, but the ceiling is all white, and definitely reflects a ton of light. Also the screen is huge, so when its a bright scene it is very bright. The projector im using is an Epson 8310, and the screen is 120" measured diagonally.
I have a home depot, lowes, and a sherwin williams nearby, so I can use any paint they have in stock.
btw Ive used behr silver screen before with pretty good results. Not sure if I should just get that again, or if something else would be better for me.
