My black rag top has a few lines all the way across the top that has a wet/sticky feel. I'm wondering if the mechanism that moves the top is leaking grease? Does anyone know what this could be? It is not on the interior head liner. I have treated my top with 303 specifically for convertibles.
All S 550 convertibles have an electric power top, there is nothing to leak. It's basically a glorified power window. Could it be something applied at the factory or something you applied that is reacting with the top material? Or reacting with what was already there?
Back in the day everyone used to put armor all on the dash and steering wheel until they discovered it left a greasy residue behind and the more you applied it the worse the greasy residue got. This sounds like a similar issue.
The S 550 verts have been around for 10 years and this is the first time I've heard about this.
