Quoted from SilverWings:
I conducted a series of tests: various glues and paints to see where the paint + glue would be compatible.
The only combination I found was lacquer paint + acrylic glue. Everything else turned into globs of snot, unshootable goop, or a kind of tar like residue that was just nasty. Initially, I wanted to use oil based enamel as my paint base, but never found a glue that would work with it.
So, from my limited knowledge of this: the paint + glue used must be compatible. They must mix - not like thinner would, but at least they must not generate goopy junk that in and of itself remains basically separate from the rest of the mixture. Then, when its shot, it dries and strings up SO FAST that in mid-air, it generates the webbing.
Apart from taking 1000 frames per second video of this stuff emitting from the paint gun -- that's my *theory* on how webbing works as its applied from a sprayed source. The lacquer/glue mixture I used sprayed easily and produced webbing that had fantastic adhesion and very very low build height on the surface. Absolutely no need to sand or scrape off high spots with this it just lays down perfectly.
Your tests in the first post are very much appreciated, I just like tinkering. The glue dissolved much better this time, I think because I had a larger amount of thinner in this mixture.
