Doug was meticulous in everything related to rust bluing. From prep to the final product. If anything did not come up to his level of expectations he would go back and start again if need be. Also the number of cycles he was willing to do would put most people rust bluing to shame. And the final result showed his standards were not only very high indeed but that he could meet them.

The funny thing was that I think he was always looking for that last fraction of percentage to being perfect and even when he reduced it to a tiny fraction he never lost his desire to be rid of it completely. What we thought as perfection he saw as very good but still a challenge to do better. Even when it was impossible.
