Quoted from mbwalker:I noticed the Createx airbrush paint is water based. Apparently no problems with the moisture on the playfield?
It's waterproof once dry, so as long as you don't have **too much** moisture on the playfield, you should be good.
If you are saying that the Createx has moisture, it's ammonia based and drys very quickly.
Thin it with ammonia, clean it up before it dries with water.
