Default Weatherstrip Vendor won't answer

Bought weatherstrip from probably the most popular vender here at least for weatherstrip. We all know who.
My rear hatch weatherstrip looks like this now after a year. My order # is 16554 if vender would like to make this right
I used to have a boss that wouldn't talk to me if he knew I wasn't going to like the answer

Default Super Glue Gel

I was told to use Super Glue Gel - Surprisingly it help longer so far than whatever it was glued with originally. Overall though - Not what I expected but also I bought a low priced (cheap ? or Inexpensive ?) product

Where can you buy one that fits in the corner properly and lasts?

Some vendors offer a hatch weatherstrip that the corners are hot melted instead of glued. Never tried it, but supposedly the hot melted shouldn't separate compared to the glued ones.

I think it's pretty much assumed the glued ends will separate on most or all of them. I know at one point people were recommending to go ahead and split them open and reglue them before installing. But I wouldn't use super glue as that failed on me. But I would probably look at using a black urethane glue instead.

mine came from Corvette Rubber... and that was 12 years ago. It is only now starting to tear. They have a life span... sad that yours only lasted 1 year.

If I were trying to salvage one that was already torn in the corners, I'd use black 3M Super Weatherstrip Adhesive, and clean both surfaces scrupulously before applying.

As an aside, a very light film of dielectric silicone grease on the weatherstrip where the rear glass contacts it in the areas of the corners can go a long way to help keep this from happening. The big problem with the C4 coupe rear hatch w/s is that the hatch glass slides across the w/s more than presses down on it, in this area, as the hatch is opened and closed. This tends to put a really big sideways pull on the w/s. It's a bit of a design weakness in the shape of the hatch glass. Keeping the w/s slippery in the vicinity of the corners really helps with longevity.

Live well,

SJW

I don't think that is the issue as I've had replacements split twice and the hatch was only opened a few times.

Not my issue either as my weatherstrip was well taken care of and still split
