Oxpho-blue is a great product
Oxpho-blue is a great product for cold bluing- the liquid goes on very easily, covers evenly, and gives a nice natural appearance with a decent bluish color-I tried BIRCHWOOD Casey and it was horrible- Oxpho blue does what it claims to do - easy application, good coverage- can’t go wrong- my shotgun looks great - with a Natural sheen and appearance- Buy Oxpho-Blue!!!!
