Hi. I have just bought my second OGT. Going thru a second childhood. I had the first as a teenager and my dad had it redone so I don't have the past experience to use in doing this one. I am in the process of stripping the paint off and have came across a factory joint to the left of the bottom of the back window. It has a pretty good layer of bondo (i hope I spelled that right). No damage is evident. Should that be there?
