Side Finisher Rubber Replacement and Rear Side Window Trim Replacement

[exodus454]

I did mine with the metro stuff 2 or 3 years ago, it did turn out pretty well but this winter it started cracking again. I'm gunna have to find something slightly higher quality or more UV resistant.

Did the fix on the rear window...
Extra advice:
-put foam pipe insulation on the gutter strip after removal, so you don’t scratch it, it whips around all over the place as youre working on it
-use a heat gun to remove old adhesive tape, much faster
-figure out beforehand what pipe (~10mm) to put into the new tubing to stop it kinking and test this off line (needs to be soft and flexible)
-my rear window fixings broke upon disassembly, had to put in a temp fixing

Rant: when done, curse the designers for a poor quality, short life span part and wonder why the hell they think they can rob your wallet for the sake of 4 inches of rubber (they could have sold us the rubber insert on its own)

What did you use one your? Was this the 3M stuff? Or is that your temp setup pictured?

Have you listened to the man in the YouTube video? He mentions double sided sticky tape like 50 times, so prob pretty important. Lol. Just kidding.

I know, an hour after I watched it I keep thinking of........DOUBLE SIDED STICKY TAPE!!!

Is buying the double sided sticky tape required for reassembly? I see the 3M product has is it and it is not used per the 1st video, but do you need it for the other OE piece to go back on correctly?

I’m not using double sided tape. Not needed. I have the passenger side done, working on drivers now.

Not required to attach the frame to the body, screws do a great job already at that. I haven’t heard any kind of rattling or air noise for not running the tape between the frame and the body.

I used the 3M, bought it off eBay. See post 1 to see everything I’ve seen people say they have used.

Did my driver side this past weekend with the Metro weatherstripping. I got a big kink but I'll go back in and stick some vacuum line in there.

I did this a long time ago on my old E46 and it turned out much better but no way I remember which weatherstripping I used. The metro one seemed too soft.

I'm having the exact same issue with the Metro weatherstripping. Vacuum line didn't help. Any other weatherstripping that is recommended that can be ordered online?

YES, I am JUST in the middle of planning this fix on my drivers side window. Thanks OP.

This should be added to the DIY thread, if not already.

Cheers everybody!

Big thanks to this thread as well as the video references mentioned. Just tackled this last week, plastic razor blades definitely make the job so much easier. I used Adam's TAR to remove the adhesive which worked like a charm: https://adamspolishes.com/products/adams-tar

Regarding the adhesive for the side trim: this came up in the previous version of this DIY on m3f.net. Someone in there suggested 3M General Purpose Adhesive Remover and some plastic razor blades. The key is to begin scraping while the old adhesive is still wet with the remover. Within a couple seconds of soaking, it comes right up. Make sure you clean the area after you're finished in the case any remover may still remain on your paint.

Finished the side finisher pieces today. I am usually one to just go for the go fast goodies but going a different route with this car. I love how bmw has made it like legos and that you can rebuild the whole dang thing. The adhesive tape on these wasn't as bad to take off as the rear side window trim. I used a heat gun again and peeled off with my thumbs.
