Calling this one "Patients". This is the second pile of body filler dust. You cannot imagine how soft it is, maybe even softer than baby powder. Paint can for reference. You can't really tell in the picture, but that pile is the same height as the paint can.
Stuff like this is super annoying, especially since it came that way from the factory, and the 3 of more people that painted it before me didn't fix it. The dark green in the lower left corner is a low spot that didn't get filled in when I skinned the whole door. The dark spot to the right of it is a high spot.
