Hi Ernest,
sounds like the problem I had in one of my tanks (RV9). Built a manometer and for about 6 weeks tried everything I could think of to find my leak, finally when my neighbor opened his pool, I dunked it and found 5 pinholes around rivets in the back flange. Drilled them out, put a glob of proseal on each, squeezed them and next day No Leak. Manometer held pressure...the only changes were from barometric pressure...correlated roughly with the weather reports. If you have a leak in the skin by a rib, why not try drilling it out and replacing it with a CCR 246SS-3-2 with a big glob of proseal slathered all over it. I found that after the proseal set for about 5-6 hours, I was able to clean the outside with some MEK & elbow grease.
Hope this helps

Subject: [FlyRotary] ProSeal question
Only peripherally related to rotary engines, but I have a question about ProSeal that some of you RV guys would know.
I'm trying to seal my fuel tank, and have a pinhole under one rivet on the bottom. The tank loses about an 1"-H20 of air pressure per hour. I can't find any holes anywhere else, but I won't know for sure until I patch this one and then run another pressure test. Does the small ProSeal kit sold by Aircraft Spruce and Wicks have the ability to meter out small quantities and save the rest? This pinhole chasing will start getting expensive if I have to buy a tube after every patch.
