What is best for Pinch Seams?

I have rock rails on order and will have access to my Wrangler's pinch seams during the install process. I would appreciate advice on preventative action to take and products to use (or not) to help prevent the onset of rust in the pinch seams.

Thanks!

Are you going with 37"s or bigger? I have 315-70r-17 duratracs and have no clearance issues with the pinch seam. There are threads out here with guys cutting them and using JB Weld and painting them afterwards. If you really don't plan on 37's then leave it alone is my opinion.

I may have gotten your intent wrong I thought you may have meant cutting the pinch seam. The poster above has a nice solution with the bedliner if that's what you are after. I was talking about where the seam is near the rear tires. Good Luck.

I've seen ppl fold the pinch seam instead of cutting it seems like a good idea if you desire it mine is cut & bed lined

Thanks for the replies. I found a bed liner kit at my local W-Mart and will go with that if nothing better is suggested. I'll be installing LoD rails and numerous other protective items on the '14 JKUR once winter is over. I don't plan on oversized wheels and tires, so no cutting or lifts will take place.

Late 2013's, if we're splitting hairs here...

When you install your LOD's my I suggest taking your time and making sure you install them as good as possible when you mark the drill holes...
Project JK has a good write on it... it's the one that will come with the rails.
also I used like 3 bits before the final bit and I also got high quality tap and bit.. the bit I got wasn't the one ProjectJK said to use it was the one that met the tap size..
anyhow there is very little room for error but the LOD's are awesome... IMO.

The suggestions are welcome!! I have two new drill/tap sets on hand. They are 7/16"-20NF tap and 25/64" drill bit. That was the size pairing I found in several charts. I will get a new 1/2" drill and pick up a couple of extra 25/64" drill bits at the time. With so many holes to create it just makes sense that a person would go through more than one set of drill bits.

If I'm lucky, this will be the only time the pinch seams will be exposed and I want to do the right thing while they are easily reached.

Thanks!

this is what I used... the tap and bit you list 25/64 and the 7/16-20NF. High quality tap and bit not one at the hardware store but from a machinist store..
at first I used a small starter bit then a 5/16 then the 25/64 but after I did about half of one side I ended up using four starter bits..
first a center punch, #4-5 to start, #10, 1/4, 5/16 then the 25/64", this saved me using two of the 25/64's, so I returned one... $10+ dollars.
I also used cutting and tapping fluid which I highly recommend.
if the hole is tapped a little out of square the bolt will go in but will be harder to start, so of course tap it as straight as possible... I also found that after the first tap running the tap thru again to clean out the threads before putting the bolt in helped a lot.
also put all the none tap hardware on when installing the LOD's for marking.. that includes one that will go thru the frame...

anyhow a lot of this is just normal install for those who do this a lot but I am a amateur. things I found that helped...

While I like the LoD stuff, this sounds like something I have no patience for. Will have to stick with the ones that bolt on in the 3 body-bolt holes.

I completely understand. LoD Rock Sliders have perhaps the most daunting installation to undertake in a home garage.

I went with sliders that covered them up. One of the main reasons I didn't go with the popular Ace sliders...hate that pinch seam sticking out through the gap and didn't want Rubi rails. These are OR-Fab sliders but I guess that doesn't help you out much since you have LoD's.

I noticed formed pinch seam covers in the LoD installation pics. 2 or 4 door versions are found here: Jeep JK Rock Sliders
Something else for me to consider. They seem to cover the seam and all the holes.

the best thing if possible is to see the sliders that your interested in person.. that helps a ton.. pictures unless they are close up and at different views are hard to view and make a decision.. for me I had seen the ACE and LODs in person and did a lot of research...
The one thing I really am happy with is the bed lined I did first.. so no matter what you go with I would do that first.. kind of back to your original post... post pics once its all done..

Agree 100% on bed lining. But, I live more than 100 miles from any town with 4X4 shops and my little town probably has about a dozen Wranglers with no rock rails that I have seen so far. The most radical Wranglers here are for mudding. I think my family is the only one around here that vacations regularly in Colorado, Montana, and Utah. There was just no way for me to compare items. Had to count on the comments I've seen in this forum and also thoroughly reviewed available install instructions and pics.

As soon as the pinch seam is accessible the bed liner will be applied. Once spring is here, I'll get the LoD rails and the various skid plates sitting in the corner of my garage installed and will take some pics.

Thanks again for the suggestions.

Just FYI...

Early 2013s were not trimmed. Ours was built October 2012 and pinch seams still needed to be trimmed.

It wasn't hard to do, just used a Harbor Freight sawsall and a metal cutting blade.

I really really liked the LOD - good choice! They were my preference until I changed my mind sort of at the last minute. I ended up with Fab Fours which like Raiderfan says "wrap" the seam in steel. Rust is not as big an issue here in Phoenix-rocks are lol! This is the last thing that pesky rock or BMW door attempting to door ding me in the mall parking lot is going to see-75 pounds (each side) of frame and body mounted powder coated steel and side armor, essentially a "side bumper"!

Be sure to post up pics once you get yours installed! Let those rocks bow down before you now!
