I can see that feeling nasty on the skin. dry them when done and you should get a long service life. mine get a gunk in the pool every now and then when I shock the pool. that helps
mainly sun fading more then anything but i had a half a can left over from doing my Bimini top thought what the hell lol, i didn't but thought it might help the sun fading some. didn't spend alot on them so yea just wanted to see what others thought on the subject...but spilling scotch on them LearDriver would suck!! atleast for the scotch!!
