Cylinder blueing (bluing)

And I did do all of mine in the basement right here and teh ol lady never said boo. No fans or ventilation at all. SO I would wager to say you are safe.

Thanks, I live to see another day.

It does smell, at least Brownells Oxpho does.  It's not overpowering but it's there.  I wear gloves when using it.

I agree.
Brownells Oxpho has a strong odor. If I smell it, it tingles my nose (not in a good way - gets nose bleeds easy -- old age?).
I try to use it in a well ventilated area.

AND always wear glove when handling chemicals (Acetone, Alcohol, diethyl either, MEK, hydrochloric acid, swimming pool chemicals, bleach, etc.)
I have a book in the shop that is useful. (MSDS binder)

Ok. It's been a while since I last used it. Now I wanna go do a sniff test....

Thanks Balogh, Emanuel, Mark Boesen, rsv1Cox, Levent Suberk and Getback. I will accept your encouragement and advice. Have sent an email to Birchwood Casey asking whether to use their Perma Blue paste, Perma Blue liquid, or Super Blue liquid. Also have an .09 cylinder with some bald spots around the exhaust ports to be touched up. Thanks to Emanuel for the balloon suggestion to protect the inside. Maybe the finger of an inflated rubber glove? Also paraffin wax the bore? In product descriptions there are comments "Super Blue is for hardened or highly polished steel" and "avoid getting Super Blue onto previous bluing",  "Super Blue gives a tougher finish". I am curious. Tee Dee cylinders are unhardened according to Sceptre/Model Aircraft review. Does that mean Super Blue should not be used or only that it is better than needed? The .051 cylinder is pretty highly polished by my standards. Would Perma Blue be better for touch-ups, blend in better with old bluing? Hopefully I will receive an answer from the manufacturer that only removes my hat. For smallest jar, Oxpho Blue $46, Perma Blue $12 on Amazon.ca. S&H reduces % difference. Visited several Toronto gun shops' web sites but found no bluing. They are endangered, gun control is being considered to stop frequent murders, gang fights. Just a day or two ago was the anniversary of the mass killing of 14 young women engineering students in Montreal. I don't understand, women have been in engineering for a long time. For example, Elsie MacGill, Queen of the Hurricanes.

I just sold Jim at jenuine-motor a Space Hopper so he could put his touches on it for a customer, sounds pretty wild he said he would send me the pics when done .

There are lots. Two deal with Birchwood Casey Perma Blue and Super Blue:

The second guy said that the results are cosmetic but not really very good rust protection. I think I remember seeing similar on Brownell's site, but they had a link to a guy who shows a technique which he says offers protection. It involves heat and might not be advisable for cylinders.
