I used Cerrobend on all the brass water tubes that I bent for the "Buckmobile" antique car. I think if you google it, you can find a video that shows the engine compartment opened so you can see the water tubing installed. You melt it in a double boiler, While the Cerrobend is melting, you run NON-DETERGENT MOTOR OIL through the tube, to allow the Cerrobend to flow during bending. Then you plug the end of the tube, pour in the Cerrobend, and you can place the filled tube in water to cool it. They actually want you to reheat the tube and alloy to about 105 degrees F. and then do the bend. It works wonderfully! I never had a kink or a problem. (Anneal the tubing before bending. Brass tube is very stiff because it is work hardened during the forming process, so it's bendability is VERY low.) After the bend, you put it in hot water, or if it won't fit in a tube with hot water, then GENTLY apply a propane torch to the tube, and the Cerrobend will pour right out into a bucket. I let it pour into ice cube trays that are shaped like tiny ice cubes, about 1/2" square. (Plastic ice cube trays work fine. I've been using mine for over 30 years with no damage to the trays at all.) That way I can melt the small amount I need for small tubes, without having to melt a huge block of Cerrobend every time. I keep the little cubes of Cerrobend in a coffee can. You can run a cloth rag through the tubing after draining, to remove any residue of oil or Cerrobend.
