I remember this "heating" thing back when I was treating my knives with Militec 1. It was the same thing I believe, but i only used to use it on my butterfly knives for the smooth action, and it was a few years ago.
But, iirc the heating was beneficial to the traits of the oil, not the metal opening its pores. Something about heating the metal for the oil to sit on, made the oil work better, to some degree. I remember using militec1 and finding it did actually work better when heating the knives up with a hair dryer, but I must admit it was a very old hair dryer that got hotter than it should, and would burn you if you used it on your head. So, I don't exactly know what that means. But, it did make a noticeable difference, to me.
Again, this was hotter than a regular hair dryer, but nothing like a heat gun.
Perhaps something similar with the heating of the Frog lube stuff? I don't know. But, after reading that thread with the guy testing all the different products, I am now also sold on Frog lube. Maybe the guy was connected to the company in some way, he said he wasn't. Either way, I always appreciate new findings, and now I'm going to try out some of this frog lube for myself to see.
Anyways, thanks for the thread. Can't wait to try some. I've been hearing more and more about this frog soup but kinda figured it was just another lube on the market, but from what I've seen now, the stuff looks pretty darn good. just my $.02 thanks for sharing.
