Funnily enough, my issue with acrylic primers isn't spraying them, it’s sanding them if any remedial work needs to be done. I’ve switched to them for my figures, but will still use cellulose primers for tanks, aircraft, etc…..
Acrylic primer (or paint) and isopropyl alcohol is a bit of a no-no though. It tends to turn the paint from a solution into a colloid gel (think gunk).
I always start an acrylic spraying session by running at least one load of water through the brush and spraying until the brush is completely dry….this removes residual cleaning agent and minimises my spraying issues.
