Quoted from gdonovan:

You don't need a lot of air compressor to do the job, cabinet took me less than 5 minutes at 40 psi, so not a lot of volume used. I spent more time looking, shoot, look, shoot, etc. I bet I could do the next one under a minute.
sweep, sweep, sweep, sweep, done.
Gun is listed- Any old school siphon gun will do I think, mine is over 30 years old. I bet you can still find them cheap.
I just cleaned up with acetone, cleans up fast.

Quoted from rlbohon3:

Ok, another silly question... are you guys using black paint for webbing or something more dark gray? It seems like the webbing I’ve seen on most games looks a little more dark gray than plain old black. Maybe it’s once mixed with glue or when it’s “slung” out to make a web pattern that it just looks lighter.
