Just took my first shot at priming some vertical stab parts with P60G2. First thought was the primer takes forever to mix to get the dark swirls out, which i'm not 100 percent sure I did ever after 10 minutes of stirring. Lots of advice here saying to spray until you just notice a color change which I did. Still seems a bit light, but maybe it will darken up by tomorrow. Or this is the way it's supposed to look.
