We have this GM03 White Metal Flux (60ml) from our Gaugemaster Paints, Thinners and Glues Range.
Flux is used to aid the flow and adhesion of solder and is very useful when de-soldering and re-soldering metals. This is a good general flux which has been designed for use on white metal kits and is very active at higher temperatures. The flux is usually carefully applied with a brush carefully and should be neutalised and cleaned after soldering
