Started pulling the interior panels out of the MJ, ripped out the carpet tonight, more rust than I was expecting given the outside condition of the vehicle, guess it was that wet carpet syndrome that got to it.
Lucky none of it is through the body, and none of it is even soft, went around and tapped on all the rusty spots with welding hammer, all if it is good and solid, and basically appears just to be a heavily pitted surface rust.
So right now the plan is to wire brush everything with rust on it, then get some POR15 and coat everything well(after I make modifications to the floor for the newer seats to bolt in), then the POR15 will get covered with the sound deadening material.
Anyone have anything else to consider for rust abatement?
Here you can see a VERY quick pass(not even 30 secs worth) of wire brush, compared to what it looked like before. I think the wire brush will work well on the surfaces I can get to, its the seam where I cannot get between, or the channel that I cannot get between, that worries me.
Of course, if this is as bad as it is after 22 years, another 22 years of equally bad rust wouldn't be the end of the world. Who knows, I somehow doubt I will still own the Jeep in 22 years(maybe, thats a long ways off)
I also found a muzzle brake under the carpet, LOL
