guys -

any advice on putting a new gasket on the chrome strip on the front edge of the rear window. i'm talking about getting the gasket into the thin groove (not the slot that goes over the window)

thanks in advance

I just did this, I had to use a flat bladed screwdriver to press it in little by little, make sure you measure the overhangs correctly from the one you are taking off because once the gasket is in the the strip there's no adjusting it. I also used a thin layer of epoxy between the strip and the rubber and the rubber and the glass. Then I trimmed to fit.
 
Chrome goes on the window first, I used some lube to press the rubber into the thin groove. I remember because I did this a few months ago and my fingers still hurt :) Also my windows move just faster than "painfully slow" and the new rubber can cause friction against the glass making them move just slower than painfully slow so a little corn starch or powder may be helpful for a little while. Hope I'm talking about the right gasket :)

not sure how you would do that as the rubber fits between the chrome and the window ... then loops around and goes into the tiny slot.

unfortunately Steve, i have already ripped the old gasket off. my guess is that it has to fit flush with the top of the chrome (the square end, not the pointed end) ... and with the end of the rubber that has the arched end. my gaskets are shaped differently at either end. does yours overlap the end of the metal?
 
Scott,

I trimmed the new rubber so that it points upwards like an upside down V with outside being longer than than the inner contact with upper door seal. I used no adhesive anywhere on the rubber, the thin rubber strip slipped pretty easily into the groove in the chrome strip. I may have used rubber lube but doubt it.
 
Here are some pics, top is pointed like Chris mentions, bottom is angled:

Peter,

maybe you are right. i put it on the window and then put the chrome strip on to align the gasket. and started it at the top ... but trying to get it into that little groove was an exercise in futility for me.

Chris + Steve ... did you put the gasket in the tiny groove first, then on the window ... or on the window first then into the tiny groove?
 
I put in a thin layer of epoxy in the big channel of the trim then put in the gasket then pressed the other side of the gasket into the tiny groove then added another thin layer of epoxy to the other side of channel onto the gasket side that goes against the window, then tapped it on with a rubber mallet and taped it in place once aligned to my satisfaction to cure overnight, this kept one end from wanting to see saw out from the other when installing. My old one had the adhesive on both sides so I repeated because I don't want it flying off. I also pinched the ends of the tiny groove a little bit to hold it in tight there. There's probably a couple ways to do this like Peter did, who knows how Hans and Franz actually did it.
 
I think I slipped it in last. Is this a case of BMW selling rubber gaskets that are too stiff like the much maligned hood seal?
 
I don't think they are too stiff, but they are unfinished and require finessing and trimming to install. Plus the small channel has to be not squeezed shut too much from years of use for the gasket to fit in.

the new gaskets aren't too stiff, but perhaps what the issue is might be that the tiny groove is not even - having been hammered onto the window.

i got it on, but it was a major PITA. but what i found out is that my chrome piece is slightly bent ... the window is straight. so it doesn't fit well.

time to order new chrome pieces 16.77 ea from tomkinson. with the new chrome pieces i am going to try to mount the gasket to the window, then put the chrome on the window and then put the gasket into the new tiny slot.
