Well this morning I sanded most of the primer off and painted white. Have a look.

First picture shows why to use guide coat. It would be real easy to miss small defects like this. You just sand until all the black is gone.

Second picture is of the wing and how much primer is sanded off. Primer is very heavy and should only be left where needed. I paint the whole airplane with a white single stage urethane ( which is alot lighter than primer. )

Third picture is of the fuse ready to blast.
