sunroof weatherstripping / seal
« on: 02:57:23 PM / 30-Jun-18 »
I tried to replace all the rubber seals/weatherstripping on the manual sunroof of my s12 hatch and it didn't go well. There are 3 rubber seals on the sunroof:

1. the seal that is on the roof of the car itself, the part number of that is 73874-21F00, replacing that was easy.
2. the seal that is on the inside of the glass sunroof that meets with the seal 1., the part number is 73873-13A01. This is supposed to be glued to the glass but the glue is not included. First I tried double sided tape but that didn't work for me, it didn't stick properly to the rubber seal, then I tried to glue it in place with some Pattex contact adhesive, this sticks to both surfaces but I didn't manage to get the seal in the proper position so I'll have to redo this. Also it looks really messy around the seal but that's because I used too much of the stuff. I wonder what glue or tape did they use when they originally put it together.
3. the seal / weatherstripping that's around the glass. The part I ordered is number 73872-01M05 but I'm not sure if it's the right part. It looks the same as the original one but when I put it on the glass it seems to be around 2 or 3 cm too big. I can't get it to fit the glass properly. Has anyone else run into this issue?

The work on sunroof is done for now, I'm not 100% satisfied with how it turned out but it's mutch better than it was before.

I ended up cutting almost 4 cm out of the seal n.3 and then gluing it back together with a thin strip of rubber on top of it the strengthen the connection.

I also had to cut small triangular piece out of it in each corner for the sunroof because it tended to crumple, or whatever is the word for it, due to compression force (?) made by the bend... well, it just refused to sit where it was supposed to, really. I did this to the seal n.2 as well.

As for glass-to-rubber adhesive, I ended up using the ultra black silicon gasket stuff for the seal n.3 which takes ages to cure but it keeps the seal where it's supposed to be and it's black. For the n.2 seal I used clear acrylic double sided tape, that was strong enough to keep it in place after I've done the relieve cuts in the corners.
