I installed 21 replacement sash kits in my house last spring and I have wood sills with aluminum wrapping them, but it doesn't come all the way inside, under the inner sash, so I made two inch strips of flashing that fit the width of the window sill, glued it with a wide bead of polly caulk like I suggested above, then closed the window on it, smooshing it in to the low spots, letting it stay thick were it needed the fill and it turned out perfect, great weather tight seal, this winter should be warm in my house!
