So I came up with a really cool idea for the back window that worked out well. Awhile ago, the zipper teeth on both my back window and soft top fabric were all messed up. I could have taken both parts to a shop to have them fixed, but then I figured the zipper would have gotten messed up again. I bought some industrial strength velcro from amazon, about 2 inches wide. I super glued one part of the velcro to the fabric on the softop that is on the bows. I took the other part of the velcro to a leather shop, where they sewed the velcro along the edges of my back window where the zipper teeth are. ( The glue on the velcro was not strong enough to stay on the plastic window). The place charged me 50 bucks to do it. So, whenever I have to put my back window up, I just have to attach the window to the piece of velcro on the soft top. Its not sealed 100%, but it does the job just fine. Throughout the winter, I put some 1 inch weather stripping tape along the inside of the window for a better seal. Whenever I wanna take my back window off, it literally takes me 10 seconds to detach it from the car. If anyone wants pictures, let me know and will be happy to post.
And if anyone else has mentioned this in the forum elsewhere, Sorry I missed it.
The velcro that I have holds up really well, especially because its lined around the entire zipper part of the back window. I have had it flop down on me a couple of times, but since its attached to the bar in tailgate, it doesn't go anywhere if thats what you mean.
"They've been making soft top zippers since the CJ era....How do you muck up JK zippers to the point of super glue and velcro?"
The girlfriend decided to take the soft top to the car wash one day while I was sleeping as a surprise. After that... it was all down hill from there. I also didn't care for it properly; never really cleaned or lubed the zippers. I could have always had the teeth repaired.. but I opted for something different.
It definitely has worked for me and is fine in the rain/snow. To be honest, I like it a lot more than the zipper itself. Let me know if you need more pics, I have a bunch of them that I recently snapped. The only pain the a$$ part was taking the back window to a shop so they can sew on the velcro and having them hold on to it for a couple days.
tonight I got my first jeep wrangler and I took the top down with no issues. I figured out the quickest way to zip it back up is to not latch back portion down before you zip up the back window partly and it makes a world of difference. This is a cool idea once the zippers ruin or something, though!
