Sausage HydrvFlash

1 bead under sill flashing. 2 beads between flashing and sill plate. I figured 10, ordered 11. Sales rep contacted me and said 12 (case) would be a bit less expensive. Good guy. So now I have 2 extra. Energy consultant suggested DOW 5200. I prefer to use product as intended. We a building a home with an expected ACH of less than .5.
