When I attempt (usually unsuccessfully) to describe what a real penetrating oil like Kroil can/does do vs. what is marketed as a penetrating oil (eg, WD-40), the resistance to change is remarkable.
While the WD-40 product actually has proven to be horrible stuff to use on guns, the marketing of the damn stuff is terribly effective.
On the farm in Nevada, I learned the value of paying up for a real penetrating oil like Kroil. We’d have bolts/nuts on equipment and implements that would resist the torque of a 3/4” impact wrench - which, if you feed it enough air, can apply over 650 ft-lbs of torque.
Douse them with WD-40, wait overnight and nothing would happen.
Douse them with Kroil, go get lunch, come back and hit them with the impact... zzzzzip! Off they’d come and the threads would be wet through and through.
I can highly recommend Kroil for use in firearms, especially freeing up parts that have been corroded into place. I’ve used it to recover guns (old .22 rifles handed down and not fired or cleaned in 40+ years) that were literally rusted shut and could not be opened with a rubber mallet until the action/bolt was soaked in Kroil and allowed to set overnight. The stuff actually works as a penetrating lube. Another use for Kroil is to soak exterior rust on blued guns, then use brass wool (available from Brownells) to *softly* brush off the red rust without stripping the remaining blue.
Of course, you’d much rather never have to deal with these scenarios with active duty weapons...
Yours is the third personal BTDT recommendation for Militec-1 I’ve seen - I’ll have to get some to try it out.
Good review of the Kroil..... I’ve got a case of it in the shop as well as some in each vehicle and my range bag. Little goes a long way.
The paperwork that comes with your order of Militec is a must read as its like the frog lube .... Strip yer metal, heat it to expand the pores and then slop on the first coat an then let it cool off on the wife’s cookie rack.....
Wipe off the excess after its cool an yer done.....
I think if your veteran or active duty Militec will send you a sample of the products.
Also take the time to look at rustpruffe . I’ve used this simple product for decades, you will lose it before you use it all..... Best stuff made for wiping down a firearm before storage or going into a humid environment where surface rust is the norm.....
