I have repeated this over and over ad infinitum on the various boards over the years and why it isn't common knowledge is beyond my comprehension.
Thread locking compounds are NOT the problem with difficult to remove flat head fasteners used on Jeeps. By the way, they are not Torx, Torx is a description of the driver used to remove any of the various fastener styles they are used on. Our Jeeps have flat head Torx, Pan-head Torx, and a couple of others.
The problem is the very large amount of contact between the countersunk hole and the head of the fastener. It is simple too much for such a small driver size especially when compared to the shank size. If you look at a normal hex head cap screw in 5/16", the head size is 1/2" or about 80% larger than the shank diameter. Inversely, a flat head Torx in the same size has a driver that is smaller than shank diameter and when you combine that with the high surface contact under the head in the countersunk hole, you have to have every thing perfect to remove them and typically only with some sort of impact for the stubborn ones.
I use a good socket driver on a small impact and if you aren't tapping it into the hole to get it past the paint, you're very likely using the wrong size.
Further, I've demonstrated the thread locker not being issue many times to folks by drilling off the head with a sharp 5/16" drill bit and then screwing the threaded section out with my fingers.
There is also the issue of a bit of galvanic corrosion that occurs between the zinc plating on the fastener and the corrosion inhibitor they use on the hinges and sheet metal.
As to the ones on the hinges at the windshield. Be very careful with them. There is a threaded nut plate they screw into inside the windshield frame that is only held in place with some bent over tabs. If you get the fastener half way out and push on it too hard, it will pop the nut plate out of the tabs and you will be cutting a hole in an obscure place to get it back where it belongs. You can not do it with the frame installed so don't do that.
