rear window replacement 2nd try
#1
Okay I already replaced this window seal once, but for some reason the lower corners still leaked. I just ripped it back out and I have the seal inside warming up.

I need some insight on anyone who has done it so I can make this the last time.

I also have an extra seal if anyone needs one. It is brand new in plastic came with my weatherstrip kit and I hope I won't need it.

I plan to strip and clean the area really well then make sure rust has not come back, I am also thinking placing cauking around it after seal is in place. A small bead of course nothing huge but I cannot afford for this to leak again and destroy all the work I have done on the inside.

Please anyone help

Humm..I'm glad the entire inside inner structure of my car is going to be sealed with rust bullet..Plus the new qtrs have spi epoxy primer on the entire inside before installation..Your up against a poor design of the rear qtr window seal..What I'm going to do on my car is lay a small bead of black silicone on the seal (fuzzie) BEFORE I install it ..I'm then going to mask off the rear corner & front & fill these areas with black silicone.Then tool it smooth & blend it to the seal .

Yeah I cleaned the surface pretty well and I sit the window in the seal, it is a little loose but I dont think that will be a big issue. I noticed that it has drip rails at the bottom running into the trunk, Ill make sure they do not get clogged up. I have heard a lot of bad things about this window and seal but I am going to make it work. I think some small sealent will be going in once I place the seal. What are you putting on your seal prior too? Thanks Q
I was reading a post from one of the techs on here and he said to use foam weatherstrip tape. I dont know what type. I see foam, rubber, and there are so many different sizes and shapes really gets confusing

I got it out , cleaned up and now I set my new rear panels in and now I dont know which rear window seal to use. They both look the same, but one of them is just harder. Not sure it will really matter, but figured someone might have some info for me

remember to put the closed cell foam down first around the ledge. put the seal around the window and put the rope inside the rubber lip so you can pull the seal around the ledge.
the foam fills the gap between the seal and the ledge.

when done you have to go back and back fill the ledge/rubber seal area with weather sealant. Spackle that sealant in right to the top, just enough so the chrome trim still fits.

90% it will still leak so it matches factory.... :-)

one mistake people make is when they install the headliner they wrap too much of the material around the rear window ledge, that will act as a big water leak, once the material is glued down, for the headline go back and trim it off the ledge give it maybe a 1/4" of overlap this way the headliner material does not go past the sealing area and act as a water bypass to the seal.

So is it face to say that either seal will work. I have two that are in good condition. I will get that foam dealer today and I got 3m dealer to go around seal window and frame once it is in. We shall see

Good luck with you're rear window. I also replaced my rear window seal recently, it's better now but if I'm out in the rain "to long" I'll still get a small amount of water into the trunk from the bottom left corner of the window. I just try to avoid getting it out of the garage when it rains but of course here in Washington you never know, it can be sunny and before you get home from a cruise raining. Keep us informed of how it turns out.

Yeah I got to go up there at lewis and it came and went and then came right back. It was not heavy just enough to make you mad.
