COLD BLUE is a cold burnisher for metals, ideal for retouching or restoring worn or scratched parts of the weapon. FIX BLUE is the fixer that guarantees exceptional durability and an excellent level of finish. COLD BLUE and FIX BLUE are sold together in 50ml PVC packs. Before applying COLD BLUE on the interested part, degrease with a solvent or better, sand with very fine sandpaper (0000) or steel or bronze wool. Clean well then apply COLD BLUE with cotton, a brush or a soaked cloth and distribute evenly over the entire surface. Leave to rest for 10/15 minutes, then apply FIX BLUE and leave to act for at least 24 hours. The 24 hours needed to act guarantee long-lasting durability and grip. If a darker finish is desired, the operation can be repeated a second time in the usual way.
