Eezox is good stuff. I also use Eezox not only for protecting my bores to my Damascus barrels but also the barrel's exterior, receiver, and other metal surfaces of the gun. What I really like about it is that it goes on wet and protects dry. Use light coats. A little goes a long way. Product will not harm wood finishes which is a plus. Simply wipe the excess away. I use it to clean the gun's metal surfaces after every shooting session and it seems cleaning gets easier the more I use Eezox and protecting the metal at the same time.
