damascus,
I understand, but I use the slow process because that is what I learned and cannot address the other processes (Belgian or others). I don't call myself a gunsmith and don't do outside work so turnaround time doesn't mean much to me, anyway I don't stand around waiting for the rusting, I can do something else while waiting. Also, in my opinion (I know what opinions are like) slow rust results in a better finish, if you have a different opinion, I respect it.
