MLG doors did not have quite as much paint on as they should have. They looked good by themselves, but when mounted on the airplane they looked like a slightly different white. Also, the edges were underpainted and carbon was visible looking at the airplane from the side. So...
Removed MLG doors. Wet sanded doors with 600 grit. Re-painted doors with 2 fairly heavy coats of white. Made sure to paint the edges. This is really really the last of the painting.
