Jeep Wranglers are somewhat unique, in that there is no cosmetic molding around the glass.
This holds true with most Jeep, Chrysler, and Dodge vehicles. This means that the pinch weld is exposed, not only to the elements, but to any onlooker’s sights.
This is why I use laminated (or coated) cold knife blades as shown to the left with the white on the neck. This will help with accidentally scratching the pinch weld, later causing rust. You should primer bare metal from a scratch, which causes a problem with the cosmetic appeal, since primer is black, and would be visible without the molding to cover. Also a patient, and knowledgeable hand and mind are crucial so as to prevent this issue altogether.
Even when taking time on a Jeep, should take no more than 30 minutes at the most. Prepping the vehicle and the glass takes under 2 minutes, and cutting it out, no more than 5 minutes.
I spend probably most of my time on this step, making sure the windshield replacement is perfectly centered and spaced on all sides. This is not only visually pleasing, but also guarantees a flawless cutout the next time it needs to be done!
