It was for a time the most preferred paint, and the best way to introduce SM into a White base. It's Gray base is quite dark, so it takes very little %-wise to darken a white to a basically neutral Gray. It has Mica flakes in abundance......very fine ones.....and at the small amounts introuduced via the small amounts of SM utilized, everything was as balanced as could be.
Butcha know, that was exactly what MMud-SE was all about, and why it worked so well. That led to PB taking interest in MMud-SE, and between us, the creation of RS-MaxxxMud, with it's use of the lighter hued Delta along with the Polyurethane. The addition of Pale Metallic Gold didn't happen until such was noted as being advantageous as a "corrective item" in BF aka Silver Fire.
Some few people were inclined to, and DID go beyond my recomendations (2-3 Oz. per 1/2 Gallon (Dark) or 2-3 Oz. per Gallon (lite).
Such a richer(Behr) SM adultrated mix would, and does push Blue, more than MMud-SE would-did because it has a preponerance of Lamp Black for "tint", but in MMud-SE, the other components mitigated that tendency to almout zilch.
It always depended on the proportions used. A little goes a long way, and too much requires a doubling of Mix volume to compensate back to square one. That then is what many both lamented their mistake of "pushing it" and gave up in despair.
And let's NOT discuss the torment and tribulations of those who tried and died at spreading pure Behr SM around as a base. Even I gave that up in favor of mixing in the Silver metallic instead. Well, that did come after Light Fusion was born, but the addition of the behr SM.....that too was an advancement because the white MMud coated LF screens were getting dissed for not working to increase contrast. With a MMud-SE coating on a Mirror, or even over a Base White, that changed dramatically. After that came ......................RS-MaxxxMud. After that came BF
...................., and well (BF
Also what would you suggest for priming the screen to get the larger size?
Start by "lightly" Feathering (via sanding) out the very leading edges of the original perimeter. Applying via Roller a "mid-viscosity" Primer.....at least as many layers as the original screen....perhaps one more. Then feathering in reverse, binging the new paint down to level with the old. Then...Prime the whole screen again at least twice, and there should be no trace of "linage"
Don't tint the Primer....rather depend upon the hue of the Top Coat, and it's being just thin enough to allow a "white Boost" on the brightest content from the outward light reflection.
For this sort of thing, a White Base is quite sufficent, but a Mirror..........divine.
