frame rust opinions needed

terrible pictures provided by the dealer, especially considering the amount of time and care they put into the professional photos on their listing. i guess if i was a dealer i wouldnt be providing professional shots of rusty underbodies, but anyway here are the pics. this is from the illinois/ohio area, so to me, this isnt too bad. worst area seem to be skid plate and axle cover surface rust. then again the pictures are potato quality and im comparing to my jeeps lol.

Re: frame rust opinions needed

Actually it does appear to be fixable from the pics that are shown. I bought my 2010 in 2014. It was a truck from Missouri. It had, I believe, a little more severe problem than the one that you have. It is totally fixable. It will take a week of hard labor to wire wheel, wire brush, sand and treat all of that rust. Remove as much as the rust as you can. Treat with a rust inhibitor and then paint it. I use rust-oleum from lowe's for both paint and rust inhibitor. Make sure you treat the tops of the frame rails and if you can remove the rear bumper and treat back of the frame because you will find the corrosion worst there. At that point you can have it coated with one of the many commercial undercoats available. A second option is instead of doing the undercoating, every spring I crawl under my fj and then treat the rust and repaint those rusty areas. It also gives me the opportunity to do a complete visual inspection while I am down there. When I go on break I will take a pic of my truck's underside so you can see how your FJ could look to. Good luck with your purchase.

Re: frame rust opinions needed

Here is the pics that I promised. As you can see I have a few little spots that need to be touched up. That is a project that will be accomplished in 3 weeks. But overall it is pretty rust free.

Re: frame rust opinions needed

I agree with Mulie. It's fixable, but lots of elbow grease required.

Re: frame rust opinions needed

Or just hit it with Fluid Film once or twice a year. It seals out the oxygen so the rust can't progress any further.

Re: frame rust opinions needed

Just a couple tips about spraying undercarriage after prep. Don't paint or get any paint on the cats or muffler unless it's high heat rated. And cover your diff breather etc also.
