In this photo from Fisher Body's Flint, Michigan Plant we see part of the answer to the question "How in the world did they make those amazing '59 Buick fins?" The process depends on being able to manufacture the very complex lower section of the rear quarter panel. The upper section is then welded to the lower. Further down the line, the seam between the two panels is then filled with lead and metal finished. Skilled craftsmen are obviously essential to produce this industrial work of art.
