OMG you are in for a treat. when you pull that seal, you will find that the rust has made its way where you cant see. i had to get a chisel and grinder to eventually get rid of everything, bondo it back up perfectly so the window sits right, and paint it all. i am still working on it as i havent found a windsheild seal. its been about 2 weeks since i drove my car. and the worst thing about it, is that my girlfriends 79 has the same problem and is next in line right after mine. it never ends
