I currently have a vinyl Coverstar pool cover which is navy in color. I thought that cover aged and degraded rather quickly, and now am on the verge of replacing it. I am wondering if perhaps a tan colored cover would last longer than a darker color cover since a lighter color presumably would reflect (rather than absorb) more UV rays than would a darker cover. Any thoughts on whether...other things being equal...lighter-colored vinyl covers degrade slower, faster, or at about the same rate as darker colored vinyl covers?
For the record, I live in a hot part of Southern California, USA, and my pool is an in-ground fiberglass pool. Also for the record, my existing cover is made of Ultragard II material, and replacement would be of Ultragard III material...not sure how much diff there is (if any) between those materials. Thanks in advance for any advice!
