re: Replacing sunroof weatherstrip (Page 1/2)
TheDigitalAlchemist OCT 06, 11:05 AM
Might need to replace the weatherstrip on an 86. Just a few questions...

1.does it just 'pull out', or is it usually glued in place?

2. what do you recommend I use to remove anything there? (3M Adhesive Remover?)

3. When installing the new one, should I apply the 3M Super Weatherstrip Adhesive on both the (cleaned) frame and weatherstrip?

(smear a thin coating on each, allow to get "tacky", then apply another thin smear on the weatherstrip and attach to frame?


Thanks in advance!

Is the old weatherstrip actually damaged?

The reason I ask is that some people mistakenly believe the weatherstrip is to blame if a bit of water leaks into the cabin when it rains. It's often just that the four drain holes are plugged. When they're clear, a Fiero can be driven in the rain with the sunroof open... and water does not enter the cabin. It's something I do all the time here on the (usually) rainy west coast of BC.

I'll email you the Drain Hole Fix. The document also includes where adhesive is to be applied when removing and replacing the seal. I tried to attach it here, but it's a document, not an image.

Thanks guys, we haven’t had a chance to examine it much yet…

Was going to say the same but Patrick addressed it first.

Didn't get a chance to really examine it- I'm not sure that the weatherstrip is sealing well against the glass. I'm aware that there are drain holes but haven't looked at it yet.
Heard that applying Castor oil can help revitalize the seal a bit. is that true?

I've used castor oil and it does help to swell the seal. It takes time, not instantaneous. Just got home and sending the file.

Sure, it's preferential to have the weatherstrip seal against the glass, perhaps more for preventing potential wind noise than water infiltration... but I just want to reemphasize, the rubber weatherstrip seal does not need to seal against the glass to keep water out as long as the four drain holes are free of debris.

I have used castor oil on my sunroof rubber weatherstrip seals... maybe twice in 25 years. I just don't see a real need for it.
