Blueing after EvapoRust treatment

Hello, has anyone used EvapoRust on a rusted barrel then blued the barrel and how did the results look? I had a .36 caliber Colt given to me that had rust all over the barrel surface, the loading lever and lighter rust on both cylinders. I did the EvapoRust treatment on them. The bare metal came out like a dark patina but you can see where the rust had scarred the surface. Has anyone tried to blue such a surface and how did it turn out. Or should I leave the Colt with bare metal? I’m looking for help on this so all responses are appreciated.
Thanks
P.S. Would a brass brush help?

ppg1949:
You need to polish the metal until you have removed 98% of the light pitting. I would start with 220 grit emery cloth and finish with 600 grit. Evapo-rust doesn't not prepare a steel surface for bluing it. A good polished surface is necessary for a fine blue finish even (and especially) if using a "home-blue" chemical. Also once you have a real good surface polish, de-grease and warm the metal to about 220 degrees before applying the blueing compound. Expect to do this a couple of times using 4")" steel wool to lightly polish away the 'rust' that forms. Once you get the expected result use a good anti-rust lubricant like Barricade or Mobil 1 motor oil to stop the chemical bluing reaction.

You can blue metal after using evapo-rust. The few times I did was touch up with touch up blue. Before blueing cleaned and removed oil I had put on after removing rust back to bare metal. That would have also removed any trace of evapo-rust. I like evapo-rust, for removing rust it is reasonably fast, not hard to use and removes even hard scale rust to bare metal. It takes all rust out of pits. It does leave some kind of residue that keeps rust from reforming for a little while. Would also probably keep blueing from working if metal not cleaned to bare metal again. When time permits will test and see but that doesnt help you now.

t'o'r'n, Thanks, I think I'm going to blue the barrel and go from there. If it is not satisfactory I'll remove the blue and use it in it's "antiqued" appearance.
Thanks again

I have friends that when they find old guns and things that are rusty and cheap or free call me. It is common for guys to get a gun for muzzleloader deer season. They shoot it a few times with the substitute black powder, never clean it and find a rusty, pitted mess next time they get it out. I will take one if it is free or cheap enough. Plug barrel, fill with evapo-rust and go from there. Have a cap and ball revolver that looked like rusty beyond salvaging. Soaked in evapo-rust and was amazed no pitting inside or out. It ain't a beauty to look at but mechanically is first class. I cleaned it and shoot as is.

t'o'r'n', I'm going to put it back together and see how it looks before trying any blueing. The bore on it is perfect, so it may become my woods gun.
Thanks for your info and input.
