I primed the special bases tonight just to practice spraying and figure out my method. Someone on reddit suggested spraying outside and bringing them inside in a well ventilated area to dry when there's too much humidity outside. The base coat seems okay-ish, but I think it would have gone better if I either sprayed them on top of the box instead of inside on the bottom of the box, or sprayed them inside of the box but on the side of the box and just sprayed one side of the base, wait 15+ min to dry, then rotate the bases and spray the other side. That way the sides of the base edge would have gotten better coverage.
But hey, that was the point of this test, to figure it out.
If it didn't take hours to get the kids to bed I'd probably have done some testing with those gun holsters and pouches, but there is always tomorrow. Slow and steady for this race.
I have also thought about only basing 5 models and then painting them before doing the other 5. Just as a psychological method of not feeling too overwhelmed on what I need to paint so I don't rush myself or avoid taking the time to do edge highlighting. Has anyone else done such a thing before? Just to prevent hampering of their painting motivation?
