Exactly......and in fact, Light Fusion was originally directed toward the use of a White surface....not Gray, overlaid against a surface decidedly more reflective than a Gloss White....a 2nd Surface (& 1st surface) Mirror.
"White Fusion" is in fact regularly done these days by those who use Thrifty White Hardboard with it's glossy white Melamine finish and apply the various SF / RS-MaxxxMudd mixes over it via spraying. The "White Fusion" refers to the Light rebounding off the white melamine and reintroducing itself back into the topmost layer of paint. Not the color of the specific Top Coat being used.
Bsims2719, what you have duplicated is the essential premise behind GOO System's application. In that sense, that means the use of a highly reflective Glossy White Base coating covered thinly with a slightly sheen-oriented Top Coat.
Nothing new there....but it always was a valid and viable premise.
It was the expense of the GOO, combined with the inability of many to effectively roll the product***
on without getting Roller marks that led me to develop Light Fusion.
But before LF came MississippiMud, (MM) a mix that actually combined the elements of both Base & Top coats into a one-step application.
Later, Silver Metallic was added in small amounts to enhance perceived contrast and deliver a better class of Color "PoP"
Your results look as good as they do not because the Black levels have improved but rather because the Whites have received an upward "reflective-oriented" kick in the pants. Once again, the perception of increased Black-oriented contrast is coming from the enhanced reflectivity of the brighter elements of the image via the action of the translucent Top Coat and Reflective Bottom coat.
As long as such enhanced reflectivity does not result in any undue amount of projected light being reflected off adjoining surfaces and returning to the screen to wash out the Black levels, you have yourself a real "Beamer" on your hands, a screen that almost assuredly can do a great job....a better one in fact....with the PJ set on low lamp mode.
Only one thing else needs to be addressed.
It can get MUCH
better........, however for what you have done...and spent, you've seemed to have obtained pretty much the pinnacle of achievement as far as using just White Paints and a Roller to make up a screen surface.
That's no small achievement. Many before you have tried and come up short and wanting. I'm glad your so pleased with your efforts.....for the lasting feeling of accomplishment is a vital part of the DIY ideal.*** GOO always advised against thinning their product, and when it had to be done, only then with 10% distilled water. In reality, it could easily be done with 30%, but then people would not have run out prematurely and have to re-order more.
Rolling always gobbles up paint far more qickly than spraying...and if you yourself had sprayed on the Top Coat, your results almost assuredly would have been even better still.
