Anybody have any clues how to dry out the foam in a wet seat. I have a good quality Cloud 9 vinyl that I mistakenly left out for a week or so and it rained several times during that period. I've tried everything to dry it out to no avail. I've even drilled the plastic base of the seat in several places hoping the water will drain. I've left it in the Florida sun for days. No luck. Every time I sit the water comes up through the sewn seams. Help?
