Re: Emergency Hole Patching Material
wet dry 700 kevlar reinforced epoxy putty has saved a lot of sinking boats and floating homes (as well as leaking swimming pools). Carried by a lot of offshore sailors. use with our without fiberglass cloth or as a glue to seal and attach patches. Of course these coatings pretty much have to be applied on the outside using the water pressure to hold and push them into place.
