I'm on Maui, I have a Polynesian Polehouse, mine has been sitting under the house with no garage for 32 years. I always keep it covered and especially when I've had to park in a lot for a day. I'm one mile from the ocean. Have had several car covers, cheapo to expensive over all those many years. They all claim a soft nap on the inside is critical, I know that's hype as its all in your head. I'm currently using a Tyvek white cover with Gust Guards since we are always having to deal with the trade winds here. The lightweight, breath-ability, waterproofness and featherweight light handling sold me. Plus they are much easier to wash and dry when they get funky from all the dust. I thought the reasonable cost would mean I would be giving up something, but not so, I like it the best of half a dozen car covers I've gone through over the years.
