Does anyone have good ideas for finding the leak location?  I'm still building.

I tested my Legacy wings by plugging all but two holes and covered the vent and fuel cap (latched) with packing tape.  I then installed barbed fittings to the two remaining threaded holes and put a party balloon over one and a tube on the other.  I then compressed the tank and balloon through the tube until the balloon was filled and capped the tube.  I checked all the plumbing and capped holes with soap bubbles, but saw no signs of leaks.  However, the balloon was partially deflated the following day.  A tied-off test balloon didn't deflate measurably, so I must presume that the air didn't bleed through the balloon.

Does anyone have any ideas for further leak tests?  I've heard of putting some freon into the tank and using a sniffer to find leaks, but doing this without false alarms within a garage seems tough.  Besides, I don't have the freon or the tester.  Has anyone tried this and if so, any suggestions?  How about other methods?

Thanks in advance for your help.
