69 Dart grille repair

I had some small welding rods for aluminium and cast that you used with a torch. I bought them from a vendor at Carl Casper's auto show in Louisville Ky. Years ago. I repaired a broken corvette grille with them and they worked great, it was cast aluminum. I can't remember the name of them, the guy was welding aluminum cans together at the show I'd like to find more of these, they worked great on thin aluminum.
