DRH,
Thanks again! I just had the enclosure installed before winterizing our boat. Too many days this past summer that could have been more enjoyable if we had ordered it with the boat last winter

I rolled (didn't fold) the pieces for their long winters nap, but didn't place any type of material to prevent the vinyl on vinly that RG warned against. I will definitely pull the enclosure out and apply the pledge (according to your method) and re-roll everything with a protective barier between rolls.
I'll update you in the spring as to how everything survived the winter
