I tried that last weekend and it almost worked. I was fishing for lakers in 105 fow and it didn't have any cracking but after about an hour water started to get under the clear coat. I think it was just from the water pressure or maybe a small blimish in the clear coat that made it fail. It would probably work fine in shallower water. I had 6 coats of nail polish on maby if I tried a few more coats it'd survive.
