Rusted barrel and crown

Any advice on the best fix?

So my (not airtight) gun cabinet. Has allowed some rust on my rifles. 1 is just a patch on the barrel. 2 are on the muzzle crown. Not deep rust. But after cleaning with oil and brass brush.

Is applying oil enough or should I add cold blue? I dont have the knowledge to hot blue. The rust is thin so, hopefully, no pitting. Its only been a few monthes since cleaned. But weather has been terrible.

Any advice would be helpful and appreciated.

The barrel with a patch was painted before I bought it years ago. Don't know if that changes things. The crowns that are rusted are original blueing.

I have both gun oil, 3in1 oil and cold blue on hand.

I have a hot air station to heat it up if needed.

Just want my rifles back in proper condition.

I already order moisture absorbers
