How well does the mustard finish protect from rust?
And could you tell me exactly what stuff I need to do that finish, as well as the process you have to go through?
Thank you in advance
Well, it's all just speculation, but from what I have read, and from what I've 'experienced', the patina keeps the red surface rust away a lil better. I still treat the knife as if it was a polished finish, though. That's just how I am. How much better does it work? I'm not completely sure, could just be all in my head.

But I have noticed a lil less surface rust forming during those rainy days.
The process is really simple, Yellow mustard and something to dab it on is all you need, really. I started with one coating, dabbed it on with paper towel, which left slight clumpy areas, which are the areas that become more lightly colored because it doesn't oxidize as well. The dark spots come from the thin areas of mustard.
The first coating I left on for around 45 minutes. Then I scrubbed it all off with a rag and dish soap. Now, you could probably stop here and be completely happy with your finish, cause I liked how mine looked at this point, but decided I wanted to darken it up a lil bit. So, I took a lil more mustard, and really tried to put as thin a layer as I could over the whole blade with minimal clumping. I let this dry about 15 minutes, and scrubbed it off with a rag and dishsoap again. It seemed to darken the already darker areas, as well as add a lil more of a patina on the lighter areas where the larger clumps of mustard were.
I hope that helps, but I'm not gonna say it's the best way to do it, just the way I did it.
Most people that I have read about doing a mustard patina just leave the initial coating on for 1 hour.
And keep in mind, every patina will look different.
Anyway, good luck if you try it out, and post pictures if you do. :thumbup:

Edit: here's a link to a thread on the ESEE forum about 1095, you might find a lil more info about patinas+rust there, if I remember correctly.
