The trim carpenter who finished my house use MDF on the windowsills in the

I trimmed a north facing bathroom window with MDF on a vinyl casement
window, fully expecting to paint it about 6 coats of oil. I injured my
elbow cleaning grout from the tiles and never got around to it. That
was 2 years ago. Even with all that moisture from the shower, and
condensation during the winter, the MDF is fine. I was really
surprised. I guess I will paint it at some point.
