Good to hear from ya Ken!
How bout some Marine grade waterproof paint/epoxy?
I think that might solve your problem.
Here is a link to an online dealer.....they sell stuff for waterproofing basements, grain silos, etc. etc. etc.
Wet Basement Waterproofing, Foundation Finishing & Flooring, Swimming Pool Deck, Roof, Concrete Floor Coating & Crack Repair, Radon Gas Mitigation
I am pretty sure you could find something locally.
But this should be a good start.
Been doing any cooking?
