Hi all. Just like some others on this thread I found my way here from zhpmafia looking to source a replacement for the coupe Shadowline trim rubber on my 2006 ZHP. Was able to get Matas' email address and contact him today. A set is now up to 431 euro not including his 10% code. So my question is, are group buys on these seals still a thing? If one is planned, I can wait, otherwise will place an order with him. Thanks.

You can email him about setting up a new GB. If that does not work out, 10% code is your best bet.

Is Marta’s the guy on eBay? Which pieces are you after exactly? The top one that goes all the way around both windows, or the bottom straight piece below the quarter windows? I ordered some a little while ago but ended up going with OE. So I just have them sitting here.

10% of 418 euro is roughly $452 usd which is the standard price on eBay fyi.

What percentage are people paying for tariffs on these? I'm thinking about ordering a set.

Bimma360—I need the top rubber (L/R) that starts at the front window and ends at the 3/4 window kink; the spot where the rubber eventually cracks. I already have the lower rubber trim (ordered from BMW) but would like to tackle both pieces at the same time.

I can contact Matas (Matthew) about a GB if there's interest here. Link: https://matthewnavis.com/product/bmw...her-stripping/

Guys don't spend $600 on rubber thats gonna crack again one day. Do the 3M seal solution and call it a day. If you're handy and you craft it right, you can't even tell the difference.

Got ya. Unfortunately, I have the extras for the bottom pieces.

Thanks for the advice, but I have to ask; what is the 3M seal solution? Prepping the car for sale this Spring and I'm kind of a stickler for originality...

Jeez let me know whatever you're selling i wanna buy it if youre buying 600 dollar window trims not even for yourself 😅

Theres a 3M seal that can be cut to size and worked into the channel of the shadowline in a way that the difference is completely indistinguisable from the outside once the trim is re-attached to the car. It is what this topic was created to show, check out post #1

I landed in the middle of this thread re: the GB, but I will read all of it. Thanks.

Guys that are running the vinyl tubing inside the tight bend..

Are you running it the entire length of the seal? Or just around the bend? If just around the bend, are you running it from the bend down to the end (where it meets the finished trim) or are you ending it before?

I am working on this now with the 7/16" OD / 5/16" vinyl tube and metro seal and want to make sure I have the tube in the correct places!
