I'm sorry if my advice was taken the wrong way. I just didn't want you to end up with what I had because someone did it wrong. Believe me its no fun having to replace wood framing. A somewhat easy fix to assure water doesnt go down into the side walls would be to keep what you have, but remove the edging and use the eternabond to go from the flat area over the edge and then put the edging back with Mortite weatherstripping cord behind it.
