Last winter we unknowingly had water trapped in the storage area of our 216 SSI. It was shrink wrapped and trapped during a warm winter. We took the wrap off and discovered most of our vinyl was badly mildewed from the inside. No method could clean it up. We tried everything. Short of replacing all of the vinyl has anyone tried painting your seats when the vinyl had just worn out? There are a few products on the market. Has anyone tried this method and what were your results?
