Rear glass

You need to use 3m bedding ang glazing compound on both the glass and body side. It's like liquid butyl and stays pliable. It's messy but the only way I know to get leak free. It comes in a caulk tube. http://3mcollision.com/3m-auto-bedding-and-glazing-compound-08509-1.html

Thanks for that. I am seeing most guys put seal on glass first. Then use a rope and a helper. I am doing this myself. I used RTV and thought I got it sealed good but one place has a small leak. already ruined my new package tray.
