My DPO sliced the vinyl on my driver's side rear trim panel. It had been riveted back on, right along the edge where it was under the weatherstripping. I needed to pull it off to replace rear speakers. I didn't want to rivet it again. Mike from DMCMW suggested Permatex The Right Stuff as an adhesive to bond the edge of the panel back to the underbody... either a solid bead for a likely permanent attachment or a few spots to hopefully allow it to be removable. I wanted it removable in case I need to get in there again. I actually did it yesterday. It seems to have worked. I'm thrilled to have that panel reattached without needing to recover it with vinyl to wrap and stick.
