i just redone a nef r92, and the gun turned out good but the cylinder has small reddish brown area's here and there and in the notches. also reddish brown places in the cylder holes, i oiled as soon as finished so i don't know what it is. it doesn't look like rust as its in small tiny streaks here and there. is this rust or what?, i can't post pics as my camera is tore up right now. i used birchwood casey perma blue. thanks

Sounds like old rust you didn't see or get off during the metal prep work.

The cold blue rust just got under it and made it pop up so you can see it now.

i kept rinsing with water and bluing, and its better but i still have a problem. the cylinder notches have brown color to it and the chambers do too. the rest of the cylinder looks fine, don't have any idea what i did wrong.

When I use Oxpho blue [cold blue], I can put oil over it and leave it over night.

But that is not the end of it. I have to clean the oil off and clean the bluing, and THEN re oil.

Otherwise, I will get rust spots, much later.

i am thinking of engine block paint, will i have to remove the bluing to put it on or can i just clean the gun good and spray it on? thanks

i went and got some dupli-color engine enamel with ceramic, i painted the whole gun. i have been trying to remove all the oil on it these last few days, seems it just keeps creeping out. it may not turn out as well as i hoped with the oil coming through the pins and around the hammer. hopefully most of it will stay on and i'll have a finish on my gun. thanks

Was the gun assembled when you painted it?

Sounds like it; therefore a redo very soon.

yes the gun is all together, i don't trust myself enough to take all the pins out and all the parts. where i really soaked the reblue with oil i have had a hard time getting all the oil removed. i've worked off and on for 2 days of wiping and using a hair dryer trying to get the oil out. the gun looks good, the only area's that i'm having trouble is at each pin and the trigger guard where it attaches to the frame. if the paint holds everywhere else i'll be fine with it. its just going to be a woods gun for me, its been in my family awhile and even though its not a expensive gun it was my fathers and he passed 5 years ago. i just want it good enough to last several more years. i can't afford anything expensive to put on it so i'm hoping this will at least protect it some. thanks

the gun barrel and frame did fine with the paint but the cylinder the paint came off after fireing. i cleaned it real good and blued the cylinder again. then again and cleaned and blued again. i even heated the metal before i blued, after i finished i left a goo amount of oil all over the cylinder. i did this yesterday and i went into the room just a few minutes ago and where i blued the cylinder its got a brownish color on it. it almost looks like dull brass color, there is some blue there but mostley a ole brown color. so i don't have much more money to put in this, so will this hurt anything if i keep it oiled? its going to be a woods gun but i don't want the rust to hurt the gun any. should i try something else?, as i'm out of blueing. or will it be ok and not get worse if i keep it oiled? thanks

I would not worry about it.
An NEF R92 has no real value to a gun collector regardless of the condition.

If you are old enough to call yourself an Old Fart?

It will not rust enough to matter in the rest of your lifetime.

it was my dads he passed 5 years ago, i just don't want to harm it any if i can help it. and i'm 46 years old, so i would like to give it to my son sometime. i know its a cheap gun but its been in my family since it was new and just want to keep it as well as i can. thanks

Well then, you should probably put away the spray paint and cold blue and pay to have it professionally refinished.

Nothing good can come of spray paint and cold blue further down the road.

Rust can happen under spray paint, and you will never know it until it's too late.

i didn't know it would rust under the paint, i thought the paint would prevent rust. i've removed the paint, the blued gun frame looks great. i don't have the money for a pro job, i'm barrely getting by now as i had to sell all my other handguns to pay bills that came up. this is my only handgun which i will keep as it was my dads, with only the cylinder needing work i may try a few different bluing products, i was hoping to carry it when i went hiking. can't understand why the birchwood casey blued the gun real good and not the cylinder, the gun almost looks like a factory job but the cylinder just wouldn't take good. thanks

Get some Brownells Oxpho-Blue.

It will work right over the rust and get rid of it while it is doing it.
