				| Primed all of the countersinks
 After I attached the access panel platenuts, I countersunk the main spar using a #40 countersink and used my scrap piece of sheet aluminum with a #6 dimple in it to check the depth of the countersink. Then I primed all of the countersinks with one swoop of the rattle can primer and wiped off the excess.
