This cold bluing formula has come back with great reviews! It is fast acting and leaves a even blotch free deep blue finish. Easy to use with great results! Wonderful for touch up or bluing the whole gun. I tried this product out and I am VERY impressed with it. It produces a very beautiful, rich blue. It is not like the dark flat black that you get from most cold blue liquids. NOTE: THIS CANNOT BE SHIPPED INTERNATIONALLY. WHEN CHECKING OUT YOU MUST CHOOSE All Chemicals and UPS AS YOUR SHIPPING OPTION. Chemicals have to go UPS and cannot go to PO boxes.
