Ah yes, that makes sense.

I like my rim strip, so it stays put. One 2" down the middle sealing both sides of the rim strip; a 2" strip on one side, edge up against the rim; a 1" strip on the other side with one edge against the rim and the other overlapping the 2nd piece.

Prolly a dozen ways to get'er done, that one worked for me.
