I just bought a 1987 28 foot Playbuoy (no rabbit ears) Apparently it has a leak for when I went out last night I had a list in the right rear. Is that pontoon compartmentalized or 1 big unit? Am I in danger of sinking the "Exxon Valdez"? My intent is to haul the trailer down and put her up the ramp and drain the plug. I also thought about putting some blow in foam but figured if tha stuff got wet I'd have a mess. Any ideas other than pulling it out to a welder? How do I find the actual spot? Will JB Weld hold til fall? or after our Ohio May 5th Gathering? Many Thanks in advance.
