Here's one of my older builds. Straight OOB, no primer, no fancy shit, just paint straight out of the pot. Perfectly fine. It's been displayed out in the open for a couple of years and the paint is just how it was on day 1. If I had thinned the paint just a little it would have passed for an airbrush job.
But sure, tell me why primer is oh so important, despite never actually having painted without and seeing for yourself there's no difference. Keep buying those rattle-cans like a good goy.
