No problem LD,
The patina might work well for some steels, but ones like 5160 will rust no matter what. Cloak had his RD7 with a patina for several hours out in the forest and by the end of the day it was littered with little rust spots throughout the blade.
Didn't work too well and he just stripped the patina and put a scotchbrite finish on it. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
