Stoner Invisible Glass Pro Ceramic Rain Repellent Coating

Recently purchased and applied this to to four vehicles. With the bottle included I was able to do all the glass on one sedan, as well as the windshield on three other sedans in the household. Application went pretty smooth without any notable issues. If you're applying a coating like this in hotter temps I would go toward the shorter time frame in the directions for removal time, and in cold temps toward the longer side. Otherwise follow the instructions and don't take any shortcuts or you could risk issues with "high spots" aka excess product that cured before removal. So far the water behavior and sheeting effect and repellancy is pretty good. If you haven't used a dedicated coating on glass before, you will notice this will repel the water noticeably better and last longer than more simple products. Can't comment yet on durability and longevity. They claim up to a year. There's many others out there, possibly better, but if you're not lucky or are in a pinch and need something available locally at a common brick and mortar store this should be a solid option.
