Rear bumper panel pushed forward when reversing into low step months ago (see photos). During heavy rainfall is it possible rain could enter this area and reach the rear seat footwell? Just trying to locate the source of a leak.
No. Incidentally I got some of that "Flex Seal" as-seen-on-tv to re-stick mine to the stuff behind it. The "Fingers" that are meant to hold it are very weak and, once bumped, do what you show in your pictures. Flex Seal is a black glue goo somewhat like RTV silicone.
