Left to right…all stored in Florida sun…tandem kayak poly boat lives there uncovered. No problems, but not much of a boat to begin with. Covered rowing shell , fiberglass recently repaired and painted. No problems yet. … Solo canoe poly boat re furbished and painted. Moved there to repair boat dock, temporary. (been a month.) No problems this time. It did have a leak at decks from gunnels with some discoloration.
The better ones inside however varnished wood boats on truck showed need for revarnish. Everything needs maintenance sooner or later.
