Thanks for your input, everybody. I'm going to strip all the pieces this evening and never use spray paint again.
For the sake of documentation, though, some answers to pluv's questions:

The first thing I ask is it the weather? High humidity can cause longer drying times. A day like today where it is 99% humidity as storms apporach, nothing is curing today.
I'm in Phoenix, so temps at mid-90s with 10-15% humidity. (I left it in an outdoor shed to dry, so average temp was probably in the mid-80s.

Second thing I ask, how tacky? Like sticky to the touch with fingerprints only where I hold it? Or when your finger across it, the paint rubs off? One can be fixed by hand painting over it or like 2DARK mentioned, clear coating over it and then hand painting. The latter though, you are SOL and need to strip the paint. No amount of layering is going to save it.
There's a lot of variance. A couple of pieces have very little tack. Some Marauder legs I had in the mix, on the other hand, are as sticky as a post-it note. (Oddly, the Marauder legs also look much glossier than the other parts, almost a high gloss even though I used a matte spray paint.)
