Birchwood Casey Perma Blue 90ml
Ideal for touching up or completely re-blueing most guns, the fast acting liquid gives a non-streaky, uniform blue-black finish to steel. To use simply apply with a swab to a clean, rust free and degreased surface for 30-60 seconds then rinse off with cold water to neutralize the chemical reaction and wipe dry. Repeating again until the desired colour is reached.
In the UK, you must be over 18 to purchase any air gun or ammunition.
