Trying to determine the best way to repair the holes in the rear bodypanels caused by the steel seatbelt brackets. Was considering welding new aluminum repair pieces, but since I can't weld, seems a bad way to learn. A friend who is a professional welder said I would need to use some body filler anyway after welding. So do I just fiberglass the holes (I've made some bigger than needed by tinkering) or pop rivet aluminum pieces then Bondo? What's the best way to paint afterwards? Any help would be appreciated.
