My dad got some of that aluminum brazing stuff from the hardware store that uses flux. I cant get this stuff to work at all. Any tips would be great, Ive never used this stuff before. The directions just say clean parts with sand paper or wire brush, apply flux then heat metal until brazing rod melts. Ive dont that but it wont work to good. :wall: Any help?

you will have to get some mild acid to clean the aluminum and even then you will have some problems because it is so hard to tell when the aluminum is at the melting point. I have done it in the past and always had mixed results.
