Question about lead seam filler
From where you're at there it's ok to go with filler. You could try and fill in a couple of the lower spots a bit more, but it's definitely not easy to work lead on a near vertical surface.
If you go filler over the top, you want to knock down any high spots in the lead. You don't want to be sanding that like you'll be sanding the filler and creating fine grains of lead dust. No bueno. It looks like you've already hit it with a body file and that's the way to do it, I just knock the lead down so I know it's a little low and won't peak through the filler as I sand it down.
I also would use Evercoat's Metal-2-Metal or USC's All Metal, especially for the seams. They're a lot more durable than plastic filler, and at a seam like that it's more important. I actually don't use plastic filler at all, just Metal-2-Metal. It's harder to work and expensive, but I've never had to go back to a car I used it on to do a body repair. And some of the cars I did when I was working in my old man's resto shop have had the same paint for over 20 years now.
I did the tail panel seams on my Duster in lead recently, this is what they looked like before I went over the top with filler. That's a narrower seam though, little easier.
