I recommend black oxide from du-lite.
The dul-lite process is what the majority of US gun makers call "blued".
Any ideas where in Canada du-lite is available, or does it have to be bought strait from them in the states?
Thanks for bringing this thread back to the top, lejarretnoir, I spotted it just in time to cancel my Carswell order. I have had mixed success with their products and chalked it up to being less than expert, but it sounds like a big fat AVOID.
x2 on that - was toying with buying from them, but their prices and bad reviews have turned me off of it.
Do you mean the stuff called "tool black"? Did you use the gel or the liquid. Thanks
Any ideas where this tool black is to be found? I'm planning on experimenting with some different gun finishes this summer and may as well try a variety.
