Next batch of hives I paint I’m going to use the airless too. Picked one up for doing house painting last year. Works great with latex and primer although I usually end up the same color as the paint before the days up. As much as I hate using solvent based enamel, and the cleanup, I’m leaning that way next time to avoid the blocking issues. Latex eventually dries, but it takes year(s). Blocking is a much bigger problem with foam hives since latex paint sticks to other latex paint better than it sticks to foam! It’s a real mess when foam parts start sticking together due to paint :(
