Hi I am preparing to do my first blue job. I intend on doing rust blue. As I start sanding the receiver it will come out silver and shinny but there are many very small black dots I'm guessing rust discoloration in the metal.
Will the bluing hide these or mitigate them in any way ?
I fear if I need to sand all these out I will actually need to remove a lot of metal.

Bluing is not paint. It is so thin it canot be measured with a micrometer. It will NOT cover imperfections in the metal. Naval Jelly is rust remover- you could try some of that AFTER your polish, but before degreasing and bluing.
What we have here is... failure- to communicate.
I did a cold blue on an old Remington 514 that had a bit of rust on it. I got it as clean as possible, but you can still see a few blotches where the color looks off but it's where the worst of the rust was. So, the real work is in the prep. The blue ain't gonna hide nuttin.
A good plan executed today is better than a perfect plan executed at some indefinite point in the future.

Cold bluing is good for touch ups. If you have a lot of pitting, sand blast the metal and then blue. It will give the gun a Matte finish and totally camouflage the pits. If you don't have a way to hot blue the gun. Get a brown blue product. You can get the same results with a torch and some steel wool. Just follow the directions to a tee. To get browning to go to a dark black just takes several extra coats.
Pits don't go away but once you put a nice blue job on the gun you'll never pay attention to the small flaws. The gun will look great. I blue 3 to 4 guns a week and once the new job is put together the results are stunning. If someone thinks otherwise. They are way to anal and don't need to see your project anyways.
Ok thanks for all the great suggestions.
I do want the Matt finish, a shiny finish won't work on this gun due to metal condition.
Question: sandblasting is an avenue I will follow. Now do I use sand, bead blast, walnuts, maybe soda blast with baking soda ?
I have heard of all the above used in different applications. Sand being the most aggressive kinda scares me , don't want to round off the corners. So the guys who have done this please advise what aggregate you have used .
I sand with a medium grit silicone sand. It gives a nice even finish and removes the existing finish very quickly. So you won't round out your holes. Leave the screws in and clean them also. Blue all the parts together and they will match perfectly.
All the mediums mentioned will do an excellent job for you.
