My Dart Swinger Project!

Nice! No more Flintstone mobile.
When I was doing an old Duster, I had a few small spots like the holes you have there. I cleaned them up and used seam sealer.
I thought about using fiberglass epoxy on them smaller holes especially the one in that curve of the seat track, thats gonna be a hard spot to cut out and shape back in. Thats why I saved it for last.
