I've tried windex solution and I kept getting bubbles. Now I use a heatgun set on the lowest setting. I put it on the stand it came with and turn it on. I pass the bait in front of it to warm just a little, then I start to spray. Every few seconds I pass the bait in front of the gun and the paint dries before it has a chance to separate.
Works great and there is only the paint and water in the air. You also don't have to worry about your brush.
