69 Charger Body---Front Window frame---lower right and left corners

[Chatt69chgr]

I just removed the windshield and rubber windshield gasket and am cleaning up the body steel that was underneath the rubber gasket.  I just noticed that the two bottom corners (right and left) are leaded in.  I have a little rust here and will probably have to get the lead out to fix the rusted places.  After that, should I re-lead these areas or replace the lead with a modern plastic body material?  What product?

Dont just use lightweight filler...blast the rust, weld up the seam, and use a dense product like All Metal filler. Follow that with lightweight filler to dial in the finish.
