1100 all the way. 4043 ( and 4047) is actually an old alloy used for brazing believe it or not. Its high silicon content lowers the melting point below most wrought alloys, but it also makes the weld more brittle and unsatisfactory for sheet work. Your nose im guessing is either 2S or 3S as these were the most common at the time for body work, 1100 is the correct rod for it. Good Luck!Originally Posted by Little
