I didn't know when I started this thread, it would run this long. I have used the newer cans with the big heads, and have had issues with them clogging also. The one thing I have noticed, is that you seem to get a lot more spray from the big nozzles. It seems like if your trying to get a small amount into a small spot, you may as well forget it. I've always liked Rustoleum, but I'm still sold on their nozzles.
