Congrats. Fantastic knife - though all of the BUSSE knives are pretty much fantastic knives.
Frog Lube - I was actually pretty amazed that in outdoor weather testing for rust protection Frog Lube did better than BreakFree CLP and even EEZOX.
I might be using it myself but, I still have 6 large bottles of WeaponShield to use up. I have no complaints about WeaponShield though - I use it for everything AKA bore cleaning, lubrication, and rust protection.
I have not opened a bottle of stinky Hoppes #9 in 5 years.
