How do i know if I've applied enough kiln wash?

Hello!
I have a bunch of new molds that need to be kiln washed. With the exception of a classroom project and a frit ball project, I've only used MR-97 and thin fire paper so far. I didn't like the brush strokes I got on my classroom project, so I bought a gravity fed spray gun to apply the kiln wash. The kiln wash I'm using is what came with my Paragon kiln. I'm mixing the wash 5 water to 1 powder.
If I apply 5 coats with the sprayer, I can barely see the kiln wash. (I continuously shake the sprayer between strokes to make sure the powder stays suspended) On a couple of pieces I sprayed them until I had a consistant smooth white finish. This took about 10-12 passes. The surface on those pieces is powdery and I'm concerned that the powder will stick to the glass. I used the same wash mixture and applied 5 coats to one mold. The brush strokes look horrible and the wash gravitated to the inside angles of the mold. These particular molds are a light wheat color, not the white of a Bullseye mold.
How do I know when I've applied enough kiln wash? Should I see a solid coat or a translucent coat once it's dry?
Any advise on spraying kiln wash would be greatly appreciated!
Thanks,
Carla
