Yes, of course, anonymous is right, I should replace the sill. Better yet, I should replace the windows. But until the economy picks up or my husband wins the lottery, that's just NGH.
Not Gonna Happen.
So today I froze my fingers off and painted in wind on a tall and springy ladder.
I am not afraid of heights (like some mothers I know), it is just when I am all the way up there I get kind woozy and my painting isn't quite as good.
Anyway, the painting is done and the silicone will have to wait for another day.
