What cold blue is the best or really good? Need recommendations plz

[SLoV]

Hi,

I need some recommendations on some cold blue products.

I have some scratches and dings in my mauser I'd like to lightly touch up. I should probably use a creme i'd think so it doesn't run since the areas i'll be touching up are pretty small and contained.

The bluing is the dark M48a bluing, it's pretty shiny and it's pretty black colored.

Would the same stuff work on my 10/22?

please recommend.

thank you once again
