The body seal in the trunk is under the rear glass area. The glass shop said if I went to fix the body seal I would l would half to replace the rear glass due to more then likely it will shatter. My back window cost 250 dollars and that isn't including install so I am just undercoat my entire trunk on the inside so it can leak all it wants ant it won't cause anymore rust problems in my trunk. I have enough rust problems right know.
