New -10, pressure testing the fuel tanks. Balloon stayed inflated on first tank for 4 days. Second tank just a day. I was hoping it was a crummy balloon. Second balloon test was same. On the third test, the leak(s) finally showed. Two small leaks in the top baffle seam, one in the outboard bay 3-4 inches inside the filler, and the second, one bay inward. Pic attached.
Not QB. What is the best way to fix this?
Try cleaning and sealing the outside?
Cut a hatch on the baffle and add more Proseal on the inside seam?
Can I add new proseal over cured proseal along the inside seam (cured for > year).?
Overall, a camera inspection shows good seal inside but a little light in these two spots. I'll add fuel to tanks and test further after solving this issue.
