Hi all - I've been watching the German video for the SL500 soft top replacement and saw where some "MB sealer" was used to join the two canvas parts together at the roofline. I called the dealership and explained, with photos, the sealer being used. They had the glue used for the rest of the project, but they didn't know what I was talking about - regarding the sealer and there was no part listed. Does anyone know what this stuff is and where to get it? I'm stumped!
