I use Frog Lube but I never got how it could penetrate anything but bare metal (stainless finish). I think it'll clean and lubricate your melonite but certainly not "treat" the underlying metal, that's just my opinion though, I'd be glad to be told otherwise.
Remember this when you support the labeling and tracking of people and the complete digital takeover of commerce:
"It causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand of the forehead so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name" Revelations
"So you say your prayers and you thank the lord, for that peace maker in the dresser drawer"
