The opening molded into the upper cowl for the oil door was very rough. After cutting and fabricating the door and hinge I decided to do some fiberglass work to make the door fit better. I covered the door edges with electrical tape, buttered the recess around the door opening, and closed the door.
After the SuperFil cured I removed the door and did some sanding to clean up the filler. The fit and finish of the door is much better though more work will be required before paint.
