It is!
Had some bare metal spots after the last sanding. Got it in there to avoid surface rust with rain we had. Even in there it was a bit too windy to spray yesterday. Primer was drying quick. Started at the back. Had a good bit of gritty overspray by the time I got to the front. Especially the hood. Did not realize how bad till half was sprayed. blew the other side off with air hose. Will see when I sand it. might have to take that side back down to the paint underneath to be sure I get good adhesion all the way through the layers of paint.
