Cleaned up, deburred & primed the F-706, 707 & 708 bulkheads. None of them were shipped with blue vinyl on them and they were all tarnished to heck. took forever to get in all the nooks and crannies with a red scotchbrite pad to get all the oxidation off. Went ahead and deburred/ dressed all the edges and primed. While I was waiting for primer to dry, I moved ahead and match drilled the F-711 bulkhead assy.
