We've added a room to our house with lots of windows. It's time to build the windowsills, and my husband is planning to build them of wood as that's what he's used to. I've seen new homes with acrylic or some other type of windowsill and wonder if those materials are available to diy-ers, what it's called, where I would find it, if it is hard to work with. Alternatively, is there a good way to treat / coat painted wood windowsills to make them impervious to water etc from condensation, flowerpots, ...
