Welding or Brazing Aluminium !?.. I saw a u tube welding Ali sheet and parts, with Propane, the results looked good and easy to do. Has anyone done this or knows where to get it. Seems there is Muggyweld, Aliweld, durafix, SuperAlloy 5. But can't see anyone who sells them. And no I have not broken the car, I'm building a new "Yagi Antenea" for 80-108mhz.
