74 Dart Sport tail panel

Yes, it looks like they just bondo'd over the sun roof. I had stars in my eyes when I bought it because the first car I bought as a teenager was a Dart Sport. I still want to save it though. A friend stopped the other day and suggested having it dustless blasted, I'm going to call for a quote. I'll take a picture from the trunk to show you why I think the tail panel needs replaced.
