Flux Classic 100 Gel

 8 oz bottle

Newly reformulated – Classic 100 Gel Flux by Stellar Technical Products is a thickened liquid designed for rapid wetting and shiny solder seams when hand-soldering copper sheet metal or copper foil between stained glass pieces. Non-smoking, odorless and water-cleanable, the residues won’t stain the copper before you have a chance to wipe it clean.
