I had an impressive experience using Flame Paint from start to finish. I never had a problem with gunk getting a can started. The valve system on the can is buttery and responsive to pressure. I gave to caps the cans came with a test and thought they were decent, but I pretty much always stick to using universals and NY fats. The universals and NY fats worked flawlessly with Flame. I was especially impressed with the low-pressure cans. I was able to get thin clean lines without the overspray you get with MTN 94 at times.
