Other than Birchwood casey, is there any other good ones in canada?

Here are my steps, if you have any other steps that work for you let me know, want to play around

i got mine sandblasted
smooth out with sandpaper
Clean with acetone or break clean.
Apply cold blue.
 
If blasting, I apply right out of the cabinet.
Warming the object to be blued isn't a bad idea.

Best cold blues I have used are Oxphoblue and 44-40. Availability may be an issue. I have used Oxphoblue to refinish an entire barreled action with excellent results. Still looks good after 25 plus years.
Most all the current blues on the market will give good results for touchup, etc.
 
I never did more than touch ups, but so far the best I’ve used is from baristol, I bought it at CT locally. Seems to last longer than others and the colour is closer to real blue imo
 
I have used a lot of different cold blueing products and can say that no manufactures formula will work excellent with every piece of metal. Some will work good on a certain metal alloy but not the next. the only perfect way to find the best formula for your alloy is to have a # of manufacturers on hand and test/experiment...other than that all i can recomend is to clean what you are bluing with alcohol/gas line antifreeze and use med gloves so your skin oil doesnt contaminate again with handling.

I also do the same. But I add a rub down with 0000 steel wool for a glossy finish.
 
Another vote here for Oxpho-blue. Availability in Canada is a bit awkward, however. Most of the others work alright, but again, it depends on the steel.
I will say, I've gotten some awfully funky looking colours out of the Birchwood Casey stuff at times. Looked like a peacock feather....
 
Can’t help you with brands as all I’ve found locally was Birchwood Casey products, which I find work well if you prep the surface well.

I will clean with acetone or lacquer thinner and then 99% isopropyl alcohol, I wear nitrile gloves so I don’t get any oil from my hands on the surface as well as keeping chemicals off my skin.

I either heat up the metal with a heat gun or use hot water when I rinse between coats, buffing with 0000 steel wool. Haven’t had any issues with it not going on evenly or blotchy for the most part, if I prep/clean properly I’ve always got a nice dark colour.

I’ve posted these before, this 70’s M94 is a friend’s that I refinished and cold blued with Birchwood Casey super blue. It was stored in a soft bag in a seacan before he ended up with it, the receiver took the cold blued well which I feel I got extremely lucky with lol.

Metal prep is very important to having good results.
