Default White Paste Hatch weatherstrip

Was doing some cleaning today on a car I just purchased one Wednesday. It has basically been raining here for a week and today was the first time I gave it a once over. I found this paste multiple spots on the rear weatherstripping. Is this factory?

It's factory applied, and mess to clean out too. It was on both my '86 and '87.

You should think about gluing those two pieces back together. Without drains in the corner, water could propagate into your rear cargo area.

It's a grease to help the weather stripping move when shutting the hatch and during road travel. Its suppose to stop the weather stripping from tearing from what has been said here in the past.

I've read that you should either keep it there when replacing or if you clean it up to reapply...not sure of the type of grease it is though. My rear hatch weather stripping is bad too and probably will just keep it there when I replace mine.

I have found that the GEL type superglue works well in gluing weatherstrip. I had to cut a slit in some weatherstripping to run my XM radio antenna out to the windshield. The gel type glued it back just fine. The gel stuff takes longer to dry and doesn't run off.

My '96 had that white snot. It is a pain to clean up. I put as much back as I could when I replaced the weatherstrip.

Thank you if the help. Any recommendations on the adhesive to bring the corners together?

I still have to do my rear hatch, should I scrape out the white goo and use the 3M product above or leave the white goo as a "lubricant" as someone stated above?

1. leave the white lubricant/grease and maybe add some more white lithium or silicone lubricant.

Amazon Amazon

2. weatherstrip adhesive for gluing down the other pieces around the car

3. I would recommend using gel superglue as I mentioned above for putting the corner back together. not sure how well the
weatherstrip adhesive would work bonding that corner together, mostly based on experience gluing together weatherstrip that
I cut

I would recommend not glueing any weather stripping because you may want to adjust it after it settles in. All I glued was the ends of the A pillar. Put a little black on there and shut the door. That's it . And nothing else. Didn't even need rivets. Is an example of oh yeah add some lube on the rear hatch. Now I can rag a coat of lithium on the rear hatch channel no issues. Mine was dabbed around exactly like yours. It's grease.

That was suggested for gluing those open corners. The hatch weatherstrip should be left to "float", and not be glued in place like the A / B pillars and the doors.

It works great on the corners, but you must use the "Super", not the 3M standard adhesive.

It appears one of 2 previous owners already tried glueing the corner. If I keep it more than a couple of years I'm going to replace all the weather stripping. There is a company here in Mi that manufacturer's and sells complete kits that I'm going to look into.

That's a problem that all C4's eventually experience. That weatherstrip dries up, shrinks, and gets to a point where those corners are pulled too far apart to repair them. As long as you won't be out in the rain a lot you shouldn't have a problem.

Like many my weatherstripping is pulled apart at the corner and damaged. Can't glue together anymore.

Where is the best place to purchased new weatherstripping for the hatch????

It's been some years back but I remember seeing a company that molded a metal piece in the corner to hold it all together, can't find them now.

take your pick, might even be made by the same source, difference is price, the 1st 2 are manufacturers
