speckled rust

[old fart]

i recently bought a nef r-92 revolver, got a good deal at $85. it had little places of rust here and there. i used rem oil, wd 40, and 0000 wool, the rust came off the frame and left little dark specs in its place. is this rust too?, its almost black in color. the frame is a blue parkerized type coating that nef put on it, with a rough dull texture. the cylinder is shiny blue with specs of rust here and there, i used the 0000 wool and oil but the small rust won't come off. i have run my nail across the cylinder and i can't feel the rust but it is visible. what else can i do to get the rust off the cylinder? i hope someone can help, thanks

All hot bluing is rust.

The specs under the rust you removed are not rust now, but where the bluing oxide was removed by the rust and replaced with a different color iron oxide.

There is nothing you can do about it short of a complete polishing and hot bluing.

oh the spots don't bother me as long as it isn't rust, i just wanted to make sure i got the rust. as long as i keep it oiled do you think it will be ok? thanks
