I completed my RV8 in 2004. After 20 years and over 1,000 hours of flight, I have developed a leak in the left fuel tank. It seems to be at a seam on the rear of the tank about 10 inches from the wing root.I want to fix this the right way, and feel that removing the tank is going to be the best way. Here is the problem........ we all know how many screws have to be removed. I have not been able to get even ONE loose ! The plane was painted with a three stage catalyzed paint. I've tried cutting around the circumference of each screw head with an exacto knife to no avail. Will I have to resort to using an EZ out on every screw ? I would be very grateful for any tips from those of you who have done this job in the past.
