Something else that might work for people is this: Flex Seal. It seems like a gimmick but it isn't. It is a flexible rubberized coating which pretty much cover anything. It can fill in holes too which makes it a really nice thing for damaged woodwork. For those of you who have troubles with pooling water in your window sills, here is something you might want to try.... What you want is for the water to naturally come forward and go back into your bathtub, so you need to make the edge closer to the window higher than the part that drips back inside. You could accomplish this in a lot of ways, but the easiest might be to get a thin piece of vinyl or wood or whatever, and then a tiny dowel. Set the small dowel or rod down near the window and secure it. Add the flat piece of wood (cutting it from the length in from the window out to the edge) sand it flat, seal it, paint it whatever color you need it to be, then secure it in. This could be as simple as using silicon and creating a nice smooth edge. Then spray flex seal in the entire area. Over the sill, around all the edges and on the flat surface. This project shouldn't cost too much and probably can be accomplished by stuff you have around your house. If not purchasing material would cost you less than 40 dollars.
