My neighbor is putting up his jet ski for the winter and would like to know what to do with the seat to keep it from cracking. It will be under a car port but still semi exposed to the weather.
This is what I used on my boat seats: http://www.amazon.com/3M-Cleaner-Conditioner-Protector-8-Ounce/dp/B000R4PFFO If he doesn't have a proper cover, he should at least use a tarp (even if it is under a carport). A winter's worth of dirt and exposure is a pain to clean, and it really does shorten the life of everything (not just seat vinyl).
