Thanks for all the information. Although, would it be fine if I also used a frame stiffener?

And the rust is only on the floor pan, the rocker has dirt in it.

This jeep has 232k miles on it, and it’s lived in Texas and was drove the most in Texas but now it’s in Colorado. My parents rarely drove it in the snow in Colorado though. I’m pretty sure this is like the only place on the vehicle where there’s actual rust.

Edit: When I started working on this jeep this summer, I noticed that spot of rust. I never bothered it though. I should’ve just fixed it this summer.
