: Rear window leak

I have a 1971 Chevelle SS that has just been restored. The rear window however is leaking water into my newly restored trunk. Do I take it to a glass shop and have them remove it and reseal it or should I seal it and fill the channel under the chrome strip with sealer to avoid water from pooling there??

I am afraid the problem is a little more serious than that. If water is getting into the trunk, you have a hole in the sheet metal somewhere. That means some sort of body work.
That is the bad news, the good news is that if you are lucky, it will not be hard to hide the patch because either the trunk gasket or window seal will cover it up.
You will have to take it apart to find out what is really going on. Start with the window trim. It may become obvious after that.

good luck

usually it's the metal clips that hold the trim on, they don't get sealed well enough around them or the goop breaks away from it. first id try it myself by doing this....
remove the trim, then cut away all the old sealant around the window(leave window and sealant under it intact), then check for rust/holes (especially around the clips, if the clips are rusty then just dip them in a rust restorer. re-install them and use the 3m window sealant (black and $8/tube) and seal it all , keep in mind the stuff WILL run slowly so i'd do more at top and less at bottom, but it also shrinks a LOT so it may take a couple of "coats" to do it right, also it is a good idea to fill the bottom as much as possible so it doesn't collect water. and also check the body seam where the quarters meet the rear panel that goes under the window, they tend to leak in that seem.

I just finished repairing mine about an hour ago. After pulling the chrome trim off I couldn’t see any obvious rust or holes. I cleaned the space between the glass and the body with Spray Nine cleaner and a toothbrush. Then rinsed it out with water and blew it dry with an air gun. After it was completely dry I used 3M glass sealant, which seems to be a thin clear silicone. I applied it with a small paintbrush, the type that is used for model cars. To much build up could prevent the trim from seating properly. After everything dried I ran a hose over the window for about fifteen minutes and the trunk is dry as a bone. Hope your problem is as minor as mine was.

Good luck,
Bubba
