But now that I don't have the business anymore, the little painting I do is all without much airflow. Does the waterborne stuff you use work outside of a booth environ, or maybe high flow prep station?

I have edged out parts in the shop and it takes a bit longer to blow dry WB in the open as I can not regulate the heat like I can in the booth , but it works .
I spotted in a tri-stage bumper in my garage this spring when it was around 55 deg. I used a heat gun to dry each coat , and it came out nice
Think of a puddle of water in your shop , no air movement it takes quite awhile for it to evaporate , but if you broom it around to thin the puddle and use air to dry it, it drys much faster .
You dont lay down heavy coats with this WB , lighter coats work faster .
I dont know what CFM it requires in a booth for WB , I do know they like to see a variable speed exhaust fan on a booth for WB . We are having our booth retrofitted for WB in 2 weeks , plus it will have the dryers built in the corners to help speed the drying times . Most modern booths should be able to handle WB today , but the down draft booth I use is 27 years old and out dated , plus I have just wore the poor thing out ....... LOL

The thing is with this High Solids Clear , you need quite abit of air movement to help it dry so it wont solvent pop (heat works better with air movement ) ! Its called a single visit clear , back to back spray application , no flash times , that can be tricky if your a heavy sprayer
