That's always going to be a problem with DIY... no matter how good something is there is always someone trying to make something better. Sometimes they do improve things, sometimes though they don't. Someone could create the ultimate screen, whether it's paint or anything, and it will always be contested by someone. That's just the nature of DIY and some of the people in it is all.

To answer your question though, yes there are at least 2-3 known and proven methods that work very well with both ambient light viewing and lights out viewing. I'd have to look up the specs on your projector to get an idea of what range of gray would be best suited for your situation and then from there you can decide from the methods that fall in that range.

I've never been one to push any one particular method, it mainly depends on the individual and their situation.

I'm tied up with a few things at work right now so if I don't get back to you right away I'm sure someone else will answer up shortly with some recommendations.
