Waterproof Foot Wraps?

[turn&burn92]

My friend cut her foot and needs a waterproof foot wrap for the summer. She cut it and the stitches came out too soon, so if she can't waterproof it she can't swim this summer. Any ideas or anything would be greatly appreciated! Thanks!

NuSkin liquid bandage. It comes in a small brown glass bottle and smells like fingernail polish. Handy as a pocket on a shirt.
