I used Blue Wonder on a S&W Model 10 about the years ago, and it is holding up pretty well BUT I have found that surface rust forms on it prettu easily. That could be due to the texture I created by blasting with glass (I think that's what I used for blasting, but CRS comes into play). You must follow the instruction with BW or it just does not work at all.
I've also used Moly Resin a few times on small parts and a Charter Arms revolver. It seems to hold up well. I am about to do a complete rifle with it for the first time. We'll see how that goes.
It's not that liberals are not smart, it's just that so much of what they know isn't so.
