I have done this a couple of times with a few of mine. It def works great!~~ My question is, so everytime you take it out of the water and the coverstock is still oily and slimy to do it again? Ive done it about 3 times so far with a few of mine and they still are oily, haha! Owell, Ill keep it up and see what happens. But, with my widow, there was a drastic change~
