I have to say, I prefer BM SuperSpec for many jobs...
Just had to do what could have been a total nightmare job - fixing mistakes made by a rental tenant who "painted" his apartment.
Using interior eggshell SuperSpec, I got unbelieveable dryhide coverage - no primer, painted with navajo white, over a dark brown. Probably could have gotten away with single-coat coverage, especially since this was a rental... but gave it two coats anyway.
5 gals of Interior Eggshell SuperSpec cost me $101.06 + tx.
Oh, and Paintsmith is TOTALLY right - do NOT ever try to put a "hot-rod acrylic" thru spray equipment - no matter WHO makes it.
If you're gonna use a hybrid paint, stick to brush & roller... and keep in mind that your brush will be somewhat stiff upon next usage, if cleaned with water only.
PS: I personally will never, ever use Behr standard finishes ever again. Some of the most watery crap I've ever worked with, IMO. (although it's still better than RL!!) The last time I used Behr, I was painting my uncle's bathroom - and it took 4 coats to cover.
