Hi..Ok i have decided to use blackout fabric for my screen. Now the big question...What should i Spray it. Some research shows that White PVC Vinyl works..Altough Grey could be equally good but i think it reduces the overall Lumens (not a good option ?? ) While Silver seems to be the way to go. Anyone experimented wih paints. Perhaps Alluminium...Gloss finishes..etc...What works Best.. and Is spray painting on blackout Fabrica good idea... does it work ?? does it last ???
