Guess if you not have the intention to lower the windshield, you might as well close the gap with some kind of rubber seal (similar as to what is commonly used for closing the fender gap) for the better looks.
Congrats on new Jeep and welcome to the club. I'm curious how many of us who read this thread has gone out to check there gap. I'm betting we all did, on my way out to check mine now, lol.
