Oh, I thought you drove your car year round Andrew. But then you live further south than I do, so you probably don't get the snow like we get.
FP, I only pulled a small section out, but it went right back in. It sort of snaps in place.
I just got back from the NAPA store where I bought a silicone spray. I'm going out right now to work on it.
If they didn't have that ledge for the rubber seal to lay on, it probably wouldn't hold the water like it does.
