Anyone have suggestions on how to remedy these small separations in the zipper? Happened to me 3 times the very first time I tried to take my back window off my soft top. [sorry for the poor photo quality, but you can still see what I mean]

Here is what ChatGPT had to say:
Thanks for the clear photo — the issue looks like a zipper tooth misalignment or fabric bunching near the teeth, both common in automotive soft tops. Since the zipper slider gets stuck and can't pass that point, here’s a step-by-step process to attempt a fix:




🔧


  • Small needle-nose pliers
  • Graphite pencil or zipper lubricant (optional but helpful)
  • Patience — forcing it can make it worse



🛠️


1.​


Look closely where the slider is stuck:


  • Are the teeth bent or misaligned?
  • Is there any fabric or dirt caught in the zipper?

If any fabric or grit is visible, try to gently remove it with tweezers or a soft brush.




2.​


Rub a graphite pencil along both sides of the zipper teeth near the jam. You can also use:


  • Zipper lube (like Gear Aid Zipper Lubricant)
  • A bar of soap or wax (sparingly)



3.​


If the slider is jammed:


  • Gently try pulling the zipper slider backward a bit to see if it frees itself.
  • Wiggle it slightly side to side while pulling gently — no forceful yanking.



4.​


Sometimes the slider loosens over time and can't properly align the teeth. Try this:


  • Use needle-nose pliers to slightly squeeze the slider top and bottom together.
  • Do this gently — you're trying to realign the grip without cracking the slider.

Do this only once, and test the movement again.




5.​


If a zipper tooth looks bent or out of place:


  • Use a pin or tweezers to gently nudge it back into alignment.



🧵 If Nothing Works…​


You may need to:


  • Remove and replace the slider (zipper repair kits work well — you can match the slider size).
  • Take the top to an upholstery shop familiar with Jeep soft tops (many convertible top repair shops can do this).



Would you like help identifying your zipper size or a video guide for replacing the slider if it’s needed?
 
Thanks for the reply. It sucks because this was literally the first time I went to remove the back window and that happened in 3 places.
 
Lubing the zipper may help prevent it form happening again. I recall discussions years ago about the best lube. The only thing I remember is lip balm if you're not in a dusty environment.
 
I still don't know what do to with my current situation. It makes using the back window very unusable. Seems lube is prevention but not solution.

That's pretty much what happened to my back window the first time I zipped it on. There was no solution really. Now I don't have a back window!
 
FWIW, it has been sitting directly in the morning sunlight in ~70-74ºF temp. The day go progressively warmer, but that is about the time I tried. I am not impressed with this $2,000 top if this is what happens on first try to unzip. Bestop, do better!

P.S. I only tried to put it back on after I couldn't get it all the way off as it would come off the end, not quite aligned. FFS
 
I found my side window was like that the first time I tried to remove it. Separated like that in one place, and misaligned in another place. I tried splicing it back together but ended up forcing the zipper past the bad spots as I meticulously fed the teeth into the body of the zipper. I really thought it would be useless afterwards, but luckily everything stayed together and it works great. I keep a can of lube with me at all times now. YMMV
 
Steal a Black/Purple/CornFlower/Whatever Crayon from a kid. Color the Zipper. I also pull down on the rear corner of the top to take some tension off and that seems to help the zipper make the corners.
