Rust Prevention

The JK went on the lift yesterday to get new gears and the shop was kind enough to take some pictures for me. It's a 2014 with less than 20k miles, one NH winter under its belt and the axles and joints are riddled with rust. What are you guys doing about rust prevention? Short of sanding down the rust and repainting, is there a better cost-effective way to do this at home? Thanks!



KCCO!

I have a '15 sahara that I take to the beach a lot and it has driven through way too much salt water. My plan is to trade it in for a rubicon. I'm waiting to hear more about the upcoming redesign.

POR15 or RustBullet. Both are really great.

Check out Fluid Film. I haven't used it yet but it is going on this fall. It is an annual treatment, heard about it from XTRyan at Extreme Terrain.

Fluid Film is great to put on to help prevent further rust. I use POR15 to coat rusty surfaces and then spray them with Fluid Film to help prevent any further rust from developing.

I was looking at the PO15 and hell, if Jay Leno promotes it, it must work I'll wait until the summer after I get back to start this project.
Question about the POR15. Can I simply paint over the rust that I can't remove or reach? Or will applying over the rust cause problems down the road?

I am sure glad you posted the photo. I ordered my 2015 Willys and had it Ziebarted at the Shipping Port in Baltimore, three days after it came off the assembly line. The Jeep arrived here in Bahrain and the Jeep and I will be transferring back to Maine during November, just in time for salt and sand season. It may not be too late to address the issue.

My last JK (2010 w/ less than 40,000 miles) had very similar rust. It appears that the Jeep factory doesn't do a very good job rust prevention on its undercarriage. I like the reviews the POR15 is getting but really want to know if I have to clean off all the existing rust for it to work, or will be okay if the hard to reach areas are just painted over?

I just bought a used 2012 Rubicon and it looked like the OP's underneath it. So I got some POR15 Metal Prep and Rust Preventative paint. I sprayed on the metal prep, let it stay wet for 30 minutes, then rinsed everything off and let it air dry. Then I attacked it with the paint.

It was a PITA getting everything coated, and a few months later some of it is peeling off. I think this was due to not re-sealing the paint can well after applying the first coat as the paint was in poor shape in the can the next day. So not really the paint's fault. But whoever designed their can should be shot. Damn near impossible to open and can't be resealed.

I also bought a spray can of their Chassis Black Top Coat. This was much easier to apply than with a brush. It's expensive ($22/can from Amazon), but I figure I'll buy 1 or 2 cans once a year and keep up with spraying the underside as a cheap way to prevent rust.

It'd probably be easier painting everything up on a lift, but I didn't have that option, so the driveway it was. I did put it up on jack stands and take off the wheels though. YMMV

Chassis Saver. It is a good substitute to por15.

Looked under my 08, the only place that truely bothered me was the lap joints on the frame just in front of the front doors and just behind the rear doors had a bit of surface rust at the welds. Here in the northeast that can quickly become frame rot, so I washed it well and knocked off loose scale with a brass brush after it dried making sure not to go to clean bare metal then used a poly-metric rust converter to turn the surface corrosion into black paint in a day or so I'll wipe it all down with an rag of denatured alc. and coat it in chassis black for piece of mind. The point is por15 or general rust converters do work if I had to tell you to pick one my best advice would be to spend the little extra and go through Eastwood (you can use there generic) I have seen old rodders and nut and bolt restorers use it to a cost saving and barely noticable effect.

I was just thinking the other day that I should clean and reapply my FluidFilm before it gets cold. I love that stuff! It worked really well to preserve my frame over one salty winter and I'm sure it'll work great to do it again. I'd rather spray this stuff once a year than have to do another frame swap!
