I'm glad this worked out for you. Actually you can use chromium oxide straight off the Norton. That's what I've been doing without any issues. Ofcourse, your razor being a Boker, had a lot to do with it.
I was almost gonna go to Sarnia to take a look at a Dakota that seemed like a great deal, but arranging the logistics of it is a bit difficult. Toronto trucks are usually either dropped and riced up or abused by contractors.
