I have used Mil-Tec heated and unheated. I found the unheated Mil-Tec was not very good but heated it performed very well. I think having to heat the knife after application is a pain. I got tired of the blow dryer and used in the oven at low heat 150 degrees. It needs to be done three different times to be totally effective. This lube bonds to the metal. It is good but I find myself leaning toward Ballistol and Blue Lube. Just seems to be more time consuming to heat the knife for Mil-Tec. And I am concerned about effecting temper with heat. I think CLP Breakfree is not good one and I have had good results with applying CLP to rusted or stiff blades and cleaning rust very well and freeing up the stiff or tight blades. Works best if left over knife and then working or removing rust. Good luck.
