I have to admit I'm sensitive to odors after fifteen years of painting. Can't stand chemical smells--I ask my wife to never wear perfume. She's not to thrilled about it.
Anyway, regarding the Ace paint, it seems to dry to a nice hard finish. Surprisingly hard for being water clean up. They claim it will "smooth out" better than most paints, and I suppose it's okay but not amazing on the parts I had to brush/roll. It looks nice, though.
But the strangest thing kept happening when I sprayed the cabinet doors. I had them laid flat. I would spray on one coat (this was after priming with oil KILZ) and it would look gorgeous. Then I would spray a second coat (which I thought it needed because the cabinets were dark brown before and I'm painting them white) and I'd get thousands of these tiny pinholes in the paint. Almost invisible but you can see them if you stick your nose close. From a foot back, they look great, and I just left good enough alone. It is strange how this happened so consistently, though. I was letting the paint sit for 24 hours before second coat (says to on the can), being very careful about dust, etc.
Anyway, I like the paint but I still can't stand the "gassing off" smell. It's just not a nice smell. I trust it will go away eventually.
