working on this 1939 Ford, as stated in my other posts, this car was about 70% done when I purchased it. Of the things that need to be done are the bumpers, I got a line locally on some original 1939 Bumpers, front and rear, haven't gone to see them yet, but will be this week. The bumpers are badly rusted and pitted (from the pictures I have seen).. I plan on powder-coating them to match the paint, as I am not a fan of chrome, so they will be stripped and restored. I would like to learn how to do a lot of this work myself, rather than shipping things off to a company, so I would like to gather up some garbage metal pieces to practice on. does anyone know what type of metal the original bumpers are? Pot Metal, Steel, Aluminum?
