W123 door seals

[Guest987]

I was installing new door seals on the car. I have hit a problem on the areas that need to have adhesive used on them. I can't get the 3M super adhesive to bond to the door rubber seals. It bonds to the door ok. I have tried cleaning the rubber seals with brake cleaner, laquer thinner, & I even tried to abrade the areas a bit with sanding. The adhesive just don't adhere to the rubber. I have always used the yellow 3M, but was told this was the preferred kind to use. I have heard they use a release agent in the process of making the rubber seals to keep them from adhering to the mold, and that is the reason for the bonding issue trying to install them? Anyone have an ideas on getting past this?
