Of course, but a few good reasons not to, they take precedent.
Sizes large enough to make valid and objective decisions upon (48" x 36')at not easily done cost effectively...either with materials or shipping. A DIY'er by definition will have to purchase whatever is needed to make their own samples. The costs are comparative. And they then already have the paint necessary to make a screen.
And a lot of Members do / have done exactly that. Add to that the number of actual end users with finished screens and the number Threads & Post goes into the Thousands. The amount of vetting for Silver Fire in all it's versions since inception is extreme. But between 2004 and 2008-9, there was a "Put Up Or Shut Up" mentality as far as "proving one's Application...no matter what it was, so that many "How TO" threads about Rolling and Spraying were made and frequented...
How do you tell if your wall is flat enough to prevent blurring or geometric distortion of the projected image? How do you correct it if it is off?
Usually, any issues with the wall being bumpy...or having waves or Bows imparted by poor Framing, they are made obvious by sighting down the length of the wall. If you can visually see high & low points from the side, then you would perceive a distorted image from the Front whenever the imagery panned right or left. Just like looking through a wavy Glass window.
If one want to check for waves they cannot seem to see, using a 4' Level or similar rigid "straight edge" and moving it around on the area involved will help locate high & low points, as the straight edge will "rock" over high points or suspend across valleys. Anything that is over a 1/4" off should be filled...a daunting tasked for a unlearned DIY'er.
As for cracks, pitted spots, pinholes....and the dreaded Tape Joints, all are easily serviceable....and must be addressed because all are detrimental, the High Contrast surface will make them stand out like a wart on a Witch's nose.
And those can also be found via close inspection of a Primed or painted surface, and spot-addressed as required.
