Steven, what you're getting is "blushing", caused by humidity. Being that I live in the South, and only 30 minutes from the Atlantic Ocean, I deal with this issue on just about every paint job I do, with the only exception being Urethanes. Here's how you get around that little issue with ease!
Grab a space heater and keep it plugged in and ready when you're painting. Once you've laid down your paint, get the body/part near the heater and you can "burn" the blushing out using the heater. Don't get too close, keep the body/part a safe distance but close enough that you can feel the heat, and keep moving it to keep from melting it. After about 10 seconds, the blushing should be completely gone, and you're ready for your next coats! Repeat as needed until you're done painting!
