That sounds as if you did not power stir the S-I-L-V-E-R in the Wagner Cup container between coats. As the mix settles, water and buoyant SM particles separate from the Glaze and come forth at a far more diluted rate. You wind up misting the surface with water and sparklies.

Don't Rush it.

Don't second guess the appearance of the thinness of the application.
i was going to lay a few more coats this morning. as i feel this will cover them enough/plenty. but wow, this stuff is still a little tacky from last night(it has been raining for the last 24hrs = humid), and sinse i need the screen for tonights movie. i think i am just going to let it dry and try it out.
Absolutely not the best decision you could make. As previously stated, the repeated coats past the 2nd-3rd ones take progressively longer to dry. The Glaze acts to seal in moisture, decreasing the "evaporation rate". Only applied dry heat, ambient or directed...will decrease dry times, but applying forced heat is very risky because the "Tackiness" will grab onto dust and hair, leaving you with a blemished surface.
This is enough of an issue that I resort to "Clean room Mode' and make sure that there is no air moving in the room during the initial drying time, and even...while I spray... wear clothes that hold no lint, and wear a Hat to keep my unruly strands in place.
All that simply because the same attributes that S-I-L-V-E-R uses to make it be an exceptional performer also can serve to magnify blemishes of any type...pre-existing or introduced after a coat is applied.
Spray-induced blemishes can be / are just as bad or worse. Trying to cover such things up with successive coats is not a guaranteed solution
, mostly because to do so requires enough extra coats that therein results an excessive amount of Silver Metallic build-up on the surface...giving one a "Too Reflective" surface.
this "may" be a blessing in disguise. i can judge this mix, as well as i can with it being uneven. and decide if i want more or less silver in it.
Oh really....? Well don't dwell on that aspect too over long, because the ratio of Silver Metallic in S-I-L-V-E-R has pretty much been predetermined, and it's the number of coats applied...at what rate of speed and distance....that determines the eventual reflective properties of the end result one sees come off the surface.
One reason so many have tried using Silver Metallic mixes in the past is because of how incredibly such can effect performance. But all the same, the balance point between too little SM to make a difference, and too much so that results are unacceptable is a fine line (...or razor's edge....
) on must negotiate very cautiously, lest one slip and excise off a valuable part of one's anatomy.
and. as i said. i'm not sweat'n this. this is my first pj. so pretty much any screen will look good. and i have little invested in it, $35ish (i don't count tool cost).
so. what should i expect if i added more silver ?

I knew that was comin'
i am going to put some more coats on today. i am expecting that it will , at least, hide some of my screw ups.
You HAVE been duly warned.....so do not apply any more than 2 additional coats before testing again...and make them the type of coats done in the manne they should be don.
btw. i love this sprayer. wish i had it sooner.
I knew that was coming too.
Examine the surface as a whole...as well as how the blemishes (runs w/SM highlighted) stand out during lighter content and panning. Note how close you must get until you can obviously see any SM particles in the "good" areas. look at the entire equation and present your opinions and findings.
Only do not deviate wildly from conventional wisdom and advice. If you do...then your professed end results cannot be construed as being relevant to S-I-L-V-E-R as a whole, making the effort be re-delegated to that of a purely conjectural experiment.
Do I talk like this on the phone?
