We have several ~55G plastic (almost nylon-ish?) barrels in which

Just buy a can of that 'as seen on tv' crap and spray the bottom.
The crap to seal gutters and boat bottoms.

I want to understand why/where the failure is occurring so I can
determine if the *other* barrels are likely to fail in a similar
manner and if there is something associated with my usage/handling that
is causing the failure. Not keen on repeating the problem (which
costs me a barrel of rainwater to *detect*!) if I can avoid it!
