I have a very small leak in my hodgeman breathable waders, the leak is
in the breathable material area, not the neoprene. I tried spraying
rubbing alcohol but nothing turned purple. I tried shining a
flashlight but that didn't work either. I also tried holding the
waders under water to see if air escapes but no luck. The only thing I
can think of is to use the whole tube of aquaseal and cover a large
area to make sure I hit the leak.

Any suggestions?
