Insight Needed: Undercarriage Rust on Used 2015 JK
 

Hey all,

I’ll keep it short: Thoughts on the rust in the attached images?

I’m interested in purchasing a used 2015 JK. The Jeep was driven in several Canada winters and has some undercarriage rust. I’m moving to Central America near the beach where rust is also a concern. If I buy the car (which is out of state), I’ll have my local mechanic treat the rust and add some sort of coating before I move.

Appreciate any advice y’all may have.

I don't live in a wintery climate, but that all looks pretty normal to me from everything I've seen over the years. I've seen some pretty bad pictures. It seems like you primarily have some surface rust which is normal.

This is interesting -

Is that some sort of footpeg to stand on to reach the roof?

Awesome - that’s what I was thinking, but thought the JK Collective might have more to say on the subject.

re: the peg - that’s what I’ve assumed. Either that or a place to tie your balloons.

thanks again for the feedback.

Looks like mine. The best product I ever used which kept my (at the time) 10 year old 2007 Dodge 3500 looking like new still was Rust Check. It is a liquid they spray everywhere, I mean everywhere, and it oozes out the seams for a few weeks after but it stops rust dead in its tracks. After the first treatment then it has to be done annually for a much smaller $$ than first install. You can also get it in cans to spray on underneath if you are living down south for a long time. You need about 3 cans per year.

After doing some reading here, I used Fluid Film last year. It seems to be holding up well and keeping the rust at bay. I'll be putting a new coat on before the snow & salted roads hit

turns out it is a high Jack mount.

Not a good place to put a jack up this way. Trees will hook it and do body damage. Saw a mall crawler the other day that was so accessoried it had a side jack and every other war related equipment needed (shovels, gas cans, water etc) but it looked like it never goes offroad.

Y, that seems like a dumb place to mount a hi-lift for various reasons. Odd.
