My 70 Dart

Finished all the holes. Ground the drivers side. When I run my hand over it, it seems like it sunk in. But, before I did the passenger side I ran my hand over the places were I sanded it down. I have the dips there also, just not as bad. HUH? I worked on as many as four hole at once, meaning tack on one, then move to the next. And so on. Some places I was unable to get anything behind it, so I had to do many, many tacks. What was I going to do? Take the quarter panel off? I'll get pictures later and post them. Lunchtime here and I have some fish to cook up.
Heres a picture. Lot of spatter from flex core, but it'll clen up.
