I'm ready to proclaim my recent success with the SD/MM process. I posted some preliminary information about results with small samples in the Superplex thread a week or so ago, and at the time was only mildly positive. Well I further modified my formula and painted my whole screen last weekend, and all I can say (and the wife agrees) is WOW. A very significant improvement over white or grey(painted G24) blackout cloth. Much brighter and richer colors, somewhat better blacks, and perhaps most interesting and unanticipated is the improved detail in the image. Overall its a really significant improvement. Its better in significant ambient light as well as complete darkness, and no appreciable viewing cone.
I did go down a slightly different path than the 'official' SD/MM approach of CRMA/MissMan, but nonetheless have to give 99% credit to those guys for their groundbreaking work and incessant evangalizing
. I have a bright projector (PLV70) so I wanted to have some grey in the screen because of my positive experience with plain grey screen vs white. I also had not really been able to see much difference, with samples anyway, of the MM topcoat on plexi with or without SM backcoat. Therefore I was interested to put more 'shine' directly in the topcoat, so used silver metallic in it, plus a little bit of grey tinted white. My final recipe consisted of
4 oz deep base
5 oz UPW
8 oz Pearlescent
4 oz silver metallic
0.1/48 of lamp black (resulting from some of the UPW being actually a G24 tinted white)
Sprayed with pressure fed (not gravity) HVLP gun.
I don't mean to suggest that in all or most or some cases that this is better than the original MM topcoat, but for me I thought it gave a more pleasing result, and perhaps might have some merit for other DIYers out there.
Sorry no screenshots will be forthcoming - no digital camera. But take my word for it - it really looks good and was well worth the $150 and the time.
P.S. I have to opinionate regarding the lazy newcomers who won't read the entire thread and want the solution handed to them on a silver metallic platter - GET A GRIP. Just try to imagine the time invested to develop the content behind all those posts, and then the time spent to communicate that content. Its amazing to think that someone could complain about merely having to read the threads.
