Side Finisher Rubber Replacement and Rear Side Window Trim Replacement

[Dafoe]

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.

What have you guys found works best for removing the adhesive? Goo Gone does not seem to be cutting it.

Coincidentally I did the finisher seal repairs and horizontal seals last weekend without seeing this DIY. Wish I read this first as it would have eliminated some guesswork.

To remove the adhesive left by the horizontal trim I tried bug&tar remover, alcohol, Goof Off, and finally Wax & Grease Remover. The wax & grease remover was by far the most effective, but it still took several applications and passes with a plastic scraper to get it off. I also used a heat gun and that helped soften it up.

Just tackled the rear side window finishers today. Took about 4 hours total. What a pain in the arse. I used a heat gun and lots of adhesive remover along with a plastic scraper. Next up is tackling the side finishers.

Starting this DIY today. Thought it was a good time to tackle this since I shipped my steering wheel to Cobywheel.

I got through the driver's side of this repair yesterday in 5.5hrs - going to tackle the passenger side today. It appears you didn't pull the rear window seal off entirely - that was smart. That was a complete bear to put back on!

I did mine last year using the seal available locally from Advance Auto. Installed picture is about 7 months after install.

I am SOOOOOOOO happy that you got the "double-sided sticky tape" guy's video (the first one). I missed him...

Honestly I didn’t even notice in the few times I’ve seen it. He does say it a lot lol. I like the video as it gives some good visuals to parts that I didn’t take pictures of.

A lot of patience, a lot of adhesive remover, and a scraper.

Just finished today and what worked best for me was using plastic razor blades and soaking the adhesive with goo-gone for 5-10 minutes before scraping. Definitely still took a lot of scraping and even more patience!

I used the Metro weatherstripping about a year ago doing both side finishers. Took about 16 hours since it was my first time not knowing except what I read on line. I learned a lot doing this diy most importantly by making sure cutting a cutout for every screw holes. This was were I had the most difficult time doing the first side.

Things got easier and faster after that and I can say could be done by anyone much less time than it took me (since I’m an old man). I can probably do this now in four hours.

Reminder, the hardest screws to screw back in are the ones right after the b-pillars and by the quarter windows. Good luck!
