Utterly non-boat question ... but it does have to do with things that float, so I figured I'd shoehorn it in
. Here goes:
have a bunch of those floaty ducks for the bathtub. But, they keep squeezing water
up inside, through the hole in the bottom. Then black mold
grows inside. Once I kill the mold
(easy) and get all the water
out (moderately harder) -- is there an adhesive
I could seal off that hole with? It needs to be flexible, so it won't crack free and drop out when they play with the things, and of course not water-soluble. And pretty thick, so it will stay in the hole and not run out all over the place before it sets.
