The last time I can recall doing any lead filling was in the late 1990's, as a demonstration for my students in the high school auto body course I was teaching. It was done on a late-1960's Ford Ranchero that had a leaded seam between the cab and the quarter panels/bed sides. Lead work is one of those skills that deteriorates rapidly unless it's done frequently!
