Re: Toughest metal finish
Melonite looks promising but the access to the process might be sketchy at best. I have a barreled action that will have a moly action and stainless barrel. I will have to see if I can find anyone to get it processed for less than $200.
The HIGH temp vapor deposition seems quite scary for gun parts.
How well does Cerikote take touch up jobs? I am assuming it will not last on the bolt and raceway much better than duracoat does.
