I'm changing out the rear quarter windows on my 95 GSR. The moldings look like they have cancer. Anyway, my Helms tells me to use a body and glass "primer" when I replace them. The manual makes no mention of a specific "sealant"(other than the primers) and I know that the tape doesn't go all the way around the window. Do I buy some epoxy, or get a tube of sealant? I NEED SOME HELP ON THIS ONE?!? Thanks for anything.
