I know most of you are familiar with the rust out spot right behind the passenger seat, there's a drain plug right there... What exactly is the theory behind these anyway? Are they supposed to allow water to seep out slowly? I assume the sealant is something special that sweats water out that is pooled up on it but resists the spray it gets from underneath going down the road.
Anyway I'm wondering if I should bother trying to get the factory equivalent sealer for this plug as the old has crumbled away while I was doing some rust repairs.
What I'm getting at is, this area is ALREADY a major rust out threat even in younger Cherokee's. That's with the drain plug, if the plug does something then sealing it up would just make the area retain even more water, and rust even worse.
