mine looks the same, always wet in that area, but looks like atf for me. i am always checking the fluids and my atf is never low. less than a year ago i had my transmission rebuilt and my rear main seal replaced the same time.

I popped my rocker cover off to wax under it and found this........
I shed a bit of a tear, this is my first spot of rust on the WJ..
I drilled out the rust stripped off the clearcoat with sand paper than sprayed with spray on bedliner !! both sides than put the covers back on. That should hold off rocker replacement for a couple years at least.

Started installing my BB with new isolators. Got the front done, looks awesome so far. Hopefully going to get the rear done tomorrow. I picked up a set of Moab takeoffs last week. I'm really hoping they fit with just the BB since the tires measure about an 2 inches over stock. Also started painting the moabs satin black.
