Cold Blue Problems

[dubious]

...in general I have found that those that don't take cold blue well also don't rust much or at all.

Good to know.

After 3 rounds of heated bluing it does seem a bit darker. Back in the oil overnight. I also just received my black stainless barrel and it's more of a dark grey, so might work out.

Just outside of Victoria, BC.

Long drive from Ottawa

Interestingly enough the recoil lug turned black right away

I bought some oxpho blue from rusty wood, great so far for touch-ups.

Cold blue is not rust resistant at all!If anything it will promote rust plus it will rub off with ease .Keep it oiled and waxed

I spray brake cleaner into a rag until dripping and then wipe all surfaces to be blued 3 times with fresh rags each time. Heat the metal a bit while doing this. I also heat the metal when applying the bluing. Oxpho liquid first coat and then Oxpho paste for all coats after that. When done with bluing I heat the metal again and soak all metal with G96 and keep wet for a few days. Has worked well on everything I have tried it on so far.
Make sure rags are left open to air dry so you done get any spontaneous combustion. Gloves are nice too.

X2, heat needed for decent job.
