To the Airport!

Here is the oil door fix.

I taped the metal door in place and then from the other side attached the cut out piece with a couple pieces of fiberglass cloth and let it cure.

Then I removed the metal door. You can see the scrap glassed on in the second picture. I then filled in the area around the cutout piece with fox and let it cure. I cut it out and the new hole is what it should have looked like to begin with.
