I got the flap seal repair kit I referenced in my last post. Basically a new seal with pre-applied double sided tape. I followed the directions which told me to remove the old seal, remove any remaining adhesive from the metal edge, wipe it down with the provided alcohol pad, scuff the surface with the provided scrubby pad, apply 3M adhesive primer, wait 5 minutes, and then stick the new flap seal on. All seems fine for now. I don't like that the directions explained that the kit came with 2 flap seals, and to save the second seal for future use. Does this mean they simply expect their product to fail?
Again, for $750, I would expect a perfect product, and a smile/apology from customer service when I contacted them with the failure.
Hopefully my repair stays in place and I don't need to mess with it again.
