Wow. 1 2 3 4, 4 coats of black primer temps me to give it a little wet sanding for better airflow and to remove small dust that settled into the top coat. Hmmmm. We'll see about that later. I'm pumped I used black. Stuff looks so mean! Dude, this summer if the surface temps are less than 180 I may have a blackbird on my list :)
