Why is it that TC manufacturers build TC that will leak and you must do messy work to revitalize them periodically? Does any manufacturer used truck cargo box methods? Think about it...cargo boxes...
Wayne, my welded aluminum boat doesn't leak and is lighter than same fiberglass boat. OK pick a method of cargo box construction that is better...yes rivits have issues..use a method similar to Duroboat construction, they don't leak. http://www.duroboat.com/features.php
