I am using a combination of the velvet and flat black paint. My ventilation system covers the first 3' of width across my ceiling and comes right down to the screen frame, so I wanted to make sure to use velvet here to kill off reflections. The rest of my ceiling is about 1' above the screen which is just flat black paint right now. I wish I would have just done the whole ceiling in velvet right off the bat, but will do the remaining part (at least the first 5-6' of it out from the screen) at some point when I get a wild hair. I might even use Protostar here just for the convenience factor of the adhesive back vs having to stretch/tack the velvet which is a bit of a pain on the ceiling.
Is the Protostar adhesive good enough to stick to a drywall ceiling without fear of it coming off?
