I finally did a test to see where a grey cloud was coming from. It only seemed to appear when I used Super Spray on a darkish color (not only black). I did some tests and wherever I had brushed on Super Spray the area was cloudy. The brush I use is only for Super Spray. It doesn't seem to matter what schedule I have used. This one ramped up to 1480 and held for 10 minutes. I tested the Super Spray using dichro stringers with and without spray. I was hoping to use Super Spray instead of a cap.
Any ideas would be helpful.

You might want to apply it more evenly and thinly. I am a real fan of SuperSpray, but in my experience it only matures fully at around 1500F in my kilns and if it is applied a bit thick or allowed to puddle, it will be cloudy unless it's fully matured. When I brush it on I make sure it is never so thick that it can puddle. I will spray it on with an airbrush if the work isn't going to go up to 1500 and have never had success getting the full, clear and glossy matured finish at temps lower than 1480 in either of my kilns. Others have expressed that they get it to mature at lower temps, but I wonder if that has to do with the application...
Something to chew on.

I've found that I've had better success with applying SuperSpray with a brush if I wash it before every application. You may only use the brush for SuperSpray, but it still can get contaminated from things in your environment.
It will be cloudy if you're applying it too thick. After applying it, I tilt the piece in various directions to allow gravity to do its work, giving me smooth, even coverage.
