In the past, I have seen pictures posted of a few rifles that had the metal work treated entirely with NP3 - could anyone post pictures of a rifle or handgun that has seen a fair bit of use to show how well NP3 holds up over time? The internet is full of pictures of NP3 treated objects but most appear to be new.

I have a custom rifle in the works that I intend to be the last one I am going to ever need or want. As such, I intend to have the metal work treated in some way to enhance the rust resistance. I am considering either Cerakote or NP3 and feel that NP3 is the better option, although I have no personal experience to back that up.

Thank you

If you can't be a good example, may you at least serve as a dreadful warning
