Lost art of using Lead and not bondo

I never hear anyone say, sorry, I can't. Gotta go put lead on my car. Lol. But that work looks fantastic. I'll take a go at it. I just hate using bondo on things, seems like a cheap fix as it will fall off. Crack. And omg does it soak up paint. And then the drying time. I'll be sure and go back out there and learn that. I love being able to do things the way the factory did. And I don't want my paint job flaking up because some issue with the bondo on those stress points.
Another tool in the bag that I'll know how to do. I'm pretty sure I'll need it again some day. Just I never hear anyone asking for that kind of body work. It's always floor pans, quarter panels, and so forth. never lead work. Kinda neat though. Lead to fix dings and scratches in metal.
