XK - Rusted frame and rear axle repair

Hey Folks...
Have one issue left to address on my XK that's been bothering me for the past few years. The rear subframe and rear axle are thoroughly rusted.

It's totally visible by other drivers and just erks me.
Trying to think of options to resolve resolve this problem.

I researched potential covers to install over the frame but couldn't find anything prefab'd for the XK.

If I tackle this on my own it's going to be a huge pain. I'm really only concerned with the areas which are visible.

I take great care of my XK and detail it regularly. So I want something that won't look like junk and start peeling after a year or so.

A replacement subframe cost plus shipping is too expensive.

I'm in the Chicago area and would consider recommendations to have someone do the work for me. Send me a PM if you know someone.

It's just surface rust. Get under the Jeep with a wirewheel and/or some heavy grit sanding blocks/paper and put some elbowgrease to it. Prime it with some Rustoleum then paint it with some Rustoleum flat black.

It'll look as good as new.

Wire wheel and some wire brushes to get rid of the scale. Pressure washer to get it all clean. Let dry and hit with paint, just as mentioned above.

Next time you buy a vehicle that is rust free, get it oiled yearly so you don't have to deal with this problem because it WILL return on your Jeep. Just think what the inside of that subframe looks like...

Or clean as above and use POR15 to paint.

Thanks for the feedback.

Ya, the inside of the subframe is trashed.
I may or may not tackle this on my own. Still undecided.

If I give it a shot, I'll post some pics along the way. Not looking forward to this.

Still considering having someone do the job for me. That may be my best option because it would lessen down time without a vehicle.

Thanks again!!

Go to a local parts store and just spray some undercoating on it and you should be fine.

Regular undercoating will cover it up but not stop the rust. BUT Eastwood has a combination rust converter / undercoating I'm going to try out on mine... also IL based. And a rust converter with hose for inside frame rails.

One more thing, I have "restored" several frames, axles, etc. with wire wheeling / blasting, a coat of Rustoleum rusty metal primer and then Rustoleum satin black. It works well and is exceptionally durable. I have a rolling chassis that has sat outside for a couple years now with no fading, rust break through, etc. What helps is the rusty metal primer is oily which I think helps keep the rust from coming back. I planned on doing this to my newly purchased WK but there are so many nooks and crannies, etc., that I won't be able to reach with a wire wheel (either 4.5" on an angle grinder, or small one on a die grinder) without major disassembly that I think I am going to use the spray converter / undercoating for most under-surfaces, and only do wire wheeling and primer / satin paint on the most exposed stuff - axle, axle links, and the rear "frame" rails that are very visible. And from experience, laying on your back wire wheeling for days is awful...! But cheap and doable in your driveway.
