Ace fenders rusting...what to do?

hey JKO,
I put the ace metal fenders on my jeep about 1.5 years ago and they've started to rust kinda badly. Bubbles all over under the powder coat and it's broken through in some places. I lived in Chicago and now I'm at school down in Corpus Christi so they're both rust environments. When putting the fenders on I had to use nutserts for the rear and ended up spinning about 3 of them per side even with the nice nutsert tool. So I'm worried if I take them off to get them re powder coated ill spin more and then I won't be able to put them back on at all! Not to mention they were a pain in the ass to get on in the first place. Anyone ever had this problem with metal fenders that use nutserts? What's my best course of action to fix this rust??

Oh boy, that was helpful!

If, and that's a big if, you can get the bolts out of the "spun" nut certs you can use a small grinder tool to clean both the nut certs and Jeep sheet metal to bare metal so you could then tack weld the nutcert to the sheet metal. Make sure you use anti seize on the bolt threads when you reassemble. Another option would be to sand the fenders to bare metal, mask and paint while still on the Jeep.

Good luck, not an easy task either way.

No need to remove them, why not tape off the Jeep and paint them yourself?
Get a wire wheel to remove any loose rust, and then paint them with a spray on bedliner.

Hambo,
maybe we can assess and make sggsts for best means of gettin you rustless again if you snap a few images of the extent of the corrosion ; just sayin it is always helpful ( you'll usually get more useful advice) to post images ( we loves images) ....only if ya get a chance......

You guys have given me some good ideas thanks. Still open to any other solutions too! I'll try to post pictures in a few days. On a trip for a few days and should be back Monday.

Did you put Never-Seize on the bolts before you threaded them into the nutserts? And were they stainless bolts? If your answers are no and yes, you can probably forget about removing the fenders.

Here are some pictures of the rust. Sorry for the late reply. I think the hardware sent with the fenders that I used was stainless and I didn't use anti-seize on the bolts. Only red thread locker on the outside of the nutserts. At this point I think the best and maybe only way to do it is just grind down the rust and use rust oleum bedliner

Poor pc job. Looks like the coating is flaking off and water is getting underneath. You can try and slow it down but it's only going to get worse.
I will look to have the fenders re-coated.

I agree with kjeeper; those are not unlike my first set of 'rock ridge's taillight LED replacements that had low-budget powder coating and wound up bubbling up from moisture getting trapped beneath the PC and corners ( they replaced with aluminum ones ) ...except it seems your point of corrosion is centering on the tack weld spots for the covering plate on those fenders . I would check the integrity of the material up under ( likely trail and road gunk getting all up and under the beads and working its way thru as water will always do ...)
a full sand and resurface might save em for a few more years. Next set/if you get these fixed up , bed line them and then keep the undersides slathered with FluidFilm ....

Ugh. That's not what I was hoping to hear. So even if I sand the rust spots and recoat them with Bedliner from a can it wouldn't be worth it? And to get them re coated I would have to take the fenders off which wouldn't be easy and getting them back on would be nearly impossible. Do I have any other options??

POR-15 is a good product, but I would guess there is surface rust between the powder coat in areas that have not bubbled up yet. The OP will be chasing new rust spots forever. It would be best to do what ever is necessary to get the fenders off. Do a complete strip, prep and repaint them using high quality materials. Its a bad situation, but I feel like it is better to bite the bullet and do it right instead of it being an on going source of frustration.

they are right about POR-15; I used it to stop the progress of slight floorpan rust-out on my '95 XJ ( a spot missed by undercoating ) and it has not progressed beyond that since applying. Sand as much as you can and then coat it with the stuff.

They're going to have to come off. You'll need to blast em down, prep, primer and paint again. And if you live in the rust belt like me, get used to it...

one of the local off road shops just became a dealer for these guys. I was talking with him at a car show and he says that it's damn near indestructible with a warranty....next spring I might yank my bumpers off and see if he's right.

According to their website, they have a Lifetime Warranty.

Can't hurt to give them a call and see what they say.
