I usually take the soft top of the jeep completely and just run a safari top in the summer but its been wierd weather this year so I had the top folded back on the jeep in case of a strong storm. I went to go raise the top and all kinds of orange rust water poured out of the frame rails and all over my back seat and cargo area. i have had several generations of jeeps and have never seen this before . WTF?

 

Its easy, the frame rails are not water sealed, like the rest of the jeep, and during rain water get in them. Since your top was down for a while, the metal tubes started rusting.
