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
Harold Kovac
