Painting under OEM tailgate hinges (yeah, yeah. this again...)

Hey all,

Just wanted to get some opinions.

So I received my TF HD Hinge on Friday, but didn't get a chance to put it on over the weekend. (I didn't have my spray can of Sarge anyway so I couldn't have anyway...)

So therein lies the question: should I paint that bare metal, or just hit it with some Fluid Film (or whatever the recommended product would be for that metal/body piece)?

I can grab a can of Sarge from the dealer for 15 or 20 bucks; then probably hit it with a coat of primer and then the Sarge. Issue is I don't think I'd have the skill to blend it all in and make it seamless-ish. Then again it will be covered up by the hinge so that won't matter too much. BUUUUUUT that being said, since it will be covered, should I just hit it with rust inhibitor and call it a day?

So whaddaya say? Paint it and it doesn't have to be perfect since it'll be covered? Or just hit it with anti-rust? As you can see I'm in Ohio, so definitely need to do one or the other....

I would paint it. Just tape it off and give it a good couple of coasts, then add the protectant if you feel like.

End of the day it cannot hurt, only makes it better. I'm a paint behind the refrigerator type of guy so in this case I would paint it.

I would think since the tailgate is painted with the factory hinges in place, it sort of seals the underlying tailgate metal. Aftermarket hinges may not have the same sealing effect when installed over top of the unpainted areas.

When I upgrade my tailgate hinges, I will probably clean, prime and paint the area before installing, so as not to risk corrosion should salt and moisture seep under the new hinge. It may take a few years for corrosion to occur under a new hinge, but depending on how long you plan on keeping the Jeep, painting the area may be cheap insurance against corrosion.

I think I agree with you two; I am probably leaning more towards painting. Even if I can't blend it in perfectly clean and smooth, it'll be covered.

Paint. It's not hard to tape off and if like mine you will have to sand a bit of rust also

I taped, sanded and then used POR15 on it. Can't see it under the hinge.

I would definitely paint under it. Last year, I noticed some of the paint on my hood hinges start to peel up. I unbolted the hinges, one at a time and there was rust under them. I sanded away the rust and used Mopar color matching paint to give it all a new coat of paint.

I also changed my tailgate hinges to the Morryde hinges and I used this same Mopar paint to paint under the factory hinges.

Yep, I'm gonna clean it up, prime and paint. Gotta wait for the paint to come in. Being in Ohio I'd be shocked if it was clean underneath. Now you're making me want to check the other hinges......

Hopefully it's nice out next weekend. Thanks for the input everyone!

I painted mine when I installed the MORryde HD hinges.

Just light sanding and black RustOLeum.

Hood and carrier hinges like a worthwhile weekend preventative-maintenance project. Any other unpainted surfaces to consider? Door hinges? (Not that door alignment is exactly fun, but we're hoping to keep this thing so I'd rather be ahead of the game when it comes to rust.)

Fun Fact: Apparently FCA has the same color/paint code for 2 different colors...
-PGG: Verde Toscana (Green Metallic)
-PGG: Sarge Green

Would explain why I went to pick up my paint from the dealer and thought "What the hell is this DARK green?". Yep, Verde Toscana. Luckily they only took 2 days to get it in instead of the 7 they said when ordering; so now another 2 days later and they have my Sarge Green ready for pickup. Ready to use it this weekend!

Lesson learned. If you have a part number available (which I did), USE IT.

FCA does that a lot. Good to always remind everyone.

does anyone happen to have a list handy for the different part numbers for all colors for the JK? I should probably get a can of the Black forest green pearl just to be safe....

This doesn't list the alternate names (when the same paint is used for other models, I mean) but I was looking to match my wife's purple a few months back and this was the longest list I found (sans "P" prefix):

Well, it's all done! Got the old hinges off and surprisingly the only rust was a LIGHT layer of surface rust under the bottom hinge. Sorry, didn't take pics during; was multitasking, and got kind of a late start so was trying to finish, and so I didn't think about it.

But anyway, cleaned it all up, hit it with a couple light coats of some Rustoleum primer, and then 3 light coats of Sarge. All came out well, except that I wasn't paying attention and left on a strip of tape (the piece I used to verify tailgate alignment) and installed the TF hinge right on top of it. I pulled it off up to the edge of the hinge, then tried to shimmy the remaining piece with a little piece of paper and some micro tweezers. No luck, so now there's a little wad of tape balled up behind the hinge....oof : haha. And I barely used half a can of paint I think, guess I didn't need 2...but whenever I get some free time I might pull up all of the other hinges and spray those as well (like above).

I think good protection of the body corner hinge area is the more critical one. Because if this area will be affected by major rust-trough, this may be the hardest to fix because of how well it is structured internally and the alignment involved.

With that in mind, I wanted to do a very good job, but I must admit I failed to reach my goal (or standard) because of time. I simply should have allowed more time for the paint to fully harden out before installation.

Indeed, I believe if you install this hinge on a recently painted paint, you may risk damaging the paint in the process. Particularly with respect to the post installation adjustment. Yes, I'm fully aware that that the adjustment needs to be primarly performed on the tail gate side. However I found that some adjustment on the body side was needed as well, which in my case most likely messed up some of my half day old paint.

Bottom line, use a good paint and give it time to harden.

Some day I plan to take it off and redo it better. Perhaps look into installing a grease fitting as well.

We are in California, so I'm not in a rush, plus I have plenty of other projects ahead of this.

Loctite: I don't remember what the instruction says, but I would be cautious of using red loctite as it will make the connection essentially permanent.

When I redo mine, I will use new bolts as well and recommend everyone to have new bolt ready for the install. I'm not the type of person who strips bolt heads, but the original bolts are easy to mangle with the allen wrench provided and you can't use regular tools on some bolts for lack of adjustment accessibility.
