spray-on sealants

[skwairpeg.livejournal.com]

I was using Krylon Triple Thick for the longest time, to seal my painted furniture items. Lately I haven't been happy with the results after spraying, though. Instead of a nice clear glossy finish I was getting cloudy, hazy results. Sometimes there would be a dusty residue left behind after spraying, too. The finish was uneven and no matter how many times I sprayed over it, it wouldn't come out evenly. So I started using a different (and much more expensive) spray that I found at the craft store -- DecoArt Triple Thick. I love the way it goes on and how smooth the finish is when I'm done, but this stuff doesn't go very far at all. It's half the size of the Krylon stuff and twice as expensive. I've heard that using the Krylon stuff in humid weather might cause the problems I was having. Anyway, I'm looking for feedback about either of these sprays, or other sprays that you all use, if you use them faithfully. Any tips or suggestions?

Thanks in advance!
