Now that I have gone out and laid a heap of money down on my brand new prowler I don't want to ruin it by something I do through incorrect storage. I don't have anywhere to hang it. So if it has to sit on the carport floor will it deform it at all? Should it be on old tyres or something? Also does the afternoon sun hurt it if it hits it? What is the Ocean Kayak made of? polyethylene? does it stand up to sun. ?
