Driver Side Rocker rust and Rot

So I was underneath my 2000 wj the other day doing a routine oil change and noticed a few little rust bubbles in the undercoat on the underside of my rocker panel. I tapped it lightly with the end of my wrench and the rocker crumbled to bits i continued looking along the rocker and noticed that the rust is covering aboutt 65% of the rocker and clearly in need of a fix.

This is where i came to you guys for help, I was wondering what i should do next?

I was thinking the the first cutting away any and all rust in rot from the rocker to prevent it from spreading. but of course i cannot leave this open cavity and im not thinking a giant tub of bondo is really what i am looking for. So any suggestions that might not require me to weld in a new rocker all together?


and i forgot to mention also when wheeling the other day i managed to get a pretty decent dent in the same rocker so rocker gaurds/ rock sliders are soon to be on the way

Instead of repairing the rockers and then getting sliders you can cut the rockers off completely and replace them with (custom) rocker sliders. Lots of guys have done this and you save yourself at least a couple inches of clearance compared to the traditional bolt-on sliders.

Weld in rock sliders or weld in new rockers. Those are your only repair choices.
This isn't going to be fixed with tin, rivets, and bondo.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

i came across the same thing on mine when dealing with failing brake lines. If you search rocker here and on mallcrawlin you'll find a number of great threads showing how some people have fixed the problem.
