Wow, What a beautiful job you are doing on this car. In my books, the 1939 Lincoln Zephyr Three Window Coupes are the best looking Coupes that Lincoln produced. The 1940 models lost some of the charm of the 1939 models. That is just my opinion.
What a beautiful car! I am lucky enough to know someone here close by that has two of those. One is under restoration, and has an immaculate, perfect body.
I've never seen a 75 year old body that clean.
