E36 M3: Replacing Rear Side Window Trim and Gasket

I think this may have been the first part I ordered for this car and I finally finished up the install recently, a few months later. After a painful discovery that led to some paintwork, the E36 finally has all new trim pieces all the way around. I wanted to share my process going through this install and some of the things I learned along the way, the hard way.
Here are the parts I replaced:

This is great I got a e36 and it needs all them seals and trims redone too keep them videos coming. They are great looking cars .I'm keeping mine

[@lotmeet9382]

I've been waiting for someone to finally DIY this, thanks for sharing!

[@jeffc6832]

Uncle Matty is in his happy place, asking his favorite nephew Tommy for a hand. If it wasn't for me needing to be close to family, I'd move to FL and work my way into a job/career with OG...I think we'd get along great.

[@rf14dmb]

This was a huge help. I ordered the deteriorated outer seals a year ago but dreaded taking half the interior apart to replace them. I have the headliner out to fix that and said to myself now is the time. So thanks for showing how it goes. Not looking forward to removing the glue!

[@MrLackeydude]

For those window/door seals that cover the seam where the structure gets welding together, there is usually a notch somewhere along that sheet metal seam. For that rear quarter glass it's at the bottom center, that is the "Datum" for the seal. There will be some sort of dot on the seal and if you line up that dot with the datum then it will fit everytime. I was an engineer at a automotive oem and nearly everyone does it the same!

[@timkinley1779]

I made window sealing systems in my previous life. In some vehicles the fixed glass is encapsulated inside the molding and shipped to the assembly plant.

[@MrLackeydude]

@@timkinley1779 yeah there is some of that too. Nowadays due to NVH objectives most things or double or triple sealed.

[@timkinley1779]

@@MrLackeydude I'm referring to glass sealing systems. GM trucks and SUVs. Molded extrusion for every piece that touched glass (fixed and movable).

[@anthonya1505]

Nice work! Keep'em coming!

[@DriveFixDrive]

Nice tools. Love the videos, keep them coming!

[@Braymond141]

@Nica is correct. It's dented in two spots. Oil will help tremendously here (whatever you feel is most safe is fine), but that metal body ledge with additional paint on it always adds difficulty. My process has always been to install the lower rubber piece first, then install the roofledge trim. You also want to really push the plush seal into those corners more as well as ensure that this seal is laying flat around the entire perimeter otherwise it's like most all messed with E36 Coups, wavy. It helps to pinch close the valley that grips onto the body on this seal. Do this around the entire perimeter. I hate to say it, but you have to do it again.

[@jeffc6832]

17:50 this is a great opportunity to use some rinseless/waterless wash. I soak a demoted towel (used coating towel, etc) in my rinseless bucket to get the crud out without making too much of a mess. Really dirty areas will get "muddy" unless you are using something like ONR (or N914) that can encapsulate the dirt.

[@fuzzy333white]

Hi Matt you do not need to remove rear windows,just undo rear catch and open glass about 3 -4 inches .pull off seals ,soak glue with brake cleaner ,scrape off with plastic scraper, once removed clean ,then slide back in both seals , (start tape removal by 5mm outside )then pull off tape .while in place 30 minutes each side

[@kimnewling5728]

That was very interesting. Looked tedious. Well done.

[@alvaro969]

Gracias desde España, i have too changue this parts for my 328i e36 and u help me so much, thank u!

[@Devin.S4]

Matt, I just noticed you have the DYNAUDIO Core 47's, how do they compare to the LYD 48's. Curious since I have the Lyd's 48's and I've been wondering if it's worth the upgrade to the Core series

[@kenchimuyo2618]

can you post a link where to get new trim and gasket used in video, much appreciated! great info

[@bcastromusic]

I think those front seatbelts are still available. I know ECS says NLA but double check Schmeidmann & FCPEuro. I have replaced them before in my sedan for the very same reason... the brackets gets UV damaged and starts to crack. If money is no object and the red seatbelt buttons are faded buy new front seat belt tensioners and new rear seat belt latches. They are all available. Big difference w/ new bright red buttons.

[@zakaroonetwork777]

What do use use to clean off the Black Tar Like Glue under the Door cards? But for the Grey Glue under the trim you can use an adhesive removing Wheel.

[@Ant62419]

That’s great!! I can’t seem to find the set for my 97 SEDAN i can only find coupe/ convertible 😢

[@cwcole02]

What about your steamer? I don't think I have seen you use it - but I could have missed it.

[@wkraus_718]

Used the Koch chemie EU today actually to remove adhesive from badge removal. Worked great but got some on my tail light, it either ruined the ceramic coating ( csl,exov4) or the clearcoat. Tried polishing but still all hazy looking.

[@wkraus_718]

Works amazing on paint though lol

[@Space.335is]

Why did u replace the trim was it dented? The new one u installed is dented I feel like leave well enough alone?

[@howtodoit3074]

Do you have any links to where you purchased them

[@LabMotorsports]

I did these seals on my e36 m3 to and I was hating the car lol

[@pace628]

Getting the rubber seals in is tricky as we saw. The whole thing would have been facilitated by soapwater on the contact surfaces.

[@McMaster1500]

You can buy genuine red BMW Motorsport seatbelts front and rear from the euro E36 M3. They are still available from BMW.

[@vladoliveric9738]

Where you buy stuff for change it?

[@btverse]

I was very confused as to why the nerd3 had blue wheels. Made sense 20 min in.

[@bosoares]

Wouldn't dry ice help with all that adhesive removal?

[@ObsessedGarage]

It will once I have it set up.

[@Barbosa81]

Using a 3M Wax wheel would make that glue removal job takes 10 seconds... You should give it a try, Matt. It`s just wax so it doesn't damage paint or anything, and removes badge glue or double side tape in seconds.

[@timkinley1779]

Sounds like a good opportunity for the dry ice process. I used a wheel once and the mess it made wasn't worth the effort.

[@Barbosa81]

@@timkinley1779 What mess ? all you have is adhesive that you removed. Using the dry ice over there would make a bigger mess inside the car since there's no window there.

[@ObsessedGarage]

I've had 10 of those things. They heat up so fast and only work on some loose adhesives.

@@ObsessedGarage Cheers for the quick reply. I really love this shade and I want to respray a E92 M3 in this colour. Is there a slight variation of the techno violet? I've seen some techno violet e36s that look a little more blue-purple than magenta purple.

[@bcastromusic]

I don't care about repaint as long as it's done correctly. I can't stand people that are all about original paint and panels. No 24 yo car w/ any number of miles is going to have perfect paint. And would you rather have a bunch of freaking bondo but 'hey original panels'.. or replace the thing w/ OE part and get done right and document everything. No one could have taken care of their M3 as good as myself but it got to a point where the condition of the original paint after two decades of sun, car covers, washing, polishing, & coating was vastly inferior to the professional repaint.

[@mcubedx3]

Garage kept with heating and cooling I think is probably the best way to maintain a car for the long term.

same on compact?

That’s why I came here! I’m going to do mine to clean, and then easily remove the god awful tint. If you respond, I’ll let you know how it went and if it’s the same for compact!

[@placeholdername3206]

As an E36 owner, the E36 is really one of the worst vehicles where you wanna be "obsessed" about the fit and finish of things. It's just not a very well built car from the factory. The motor and drivetrain is bulletproof but the interior and the trim pieces inside and out are made of biodegradeable materials that just fall apart.

[@rjauto7215]

You are making something that is piss easy look like hard work fella???????

[@triplebutted]

Spoken like a guy that has never replaced the window trim on an e36 coupe.
