So I've dug through the threads and haven't really found what I need. I will be installing the quarter windows on my Cutlass once it leaves the paintshop. The question is what is the preferred method, or product to use to seal them up properly? From what I've read and video's I've watched everyone seems to use the 3M ribbon sealer butyl tape. Is the 1/4" stuff (PN#08610) a good size to ensure a good seal? I only want to do this once if possible. Thanks in advance for any advice or suggestions.
