Re: [DML] WD-40 the other side

["Don Ekhoff" <ekhoff@xxxx>]

I just talked to a friend in the firearms industry about WD-40. Turns out
he made the same mistake years ago with a whole case of expensive military
shells and guns. Upon investigation he found out that what it really does
is displace water that is on the surface and moves it along in its wicking
path. In the case of guns and ammo it will move the water along to some
crevasse inside (like a primer cap or trigger mechanism) and then bridge the
water with an oily film. That will cause corrosion and primers to fail.

Don't know how much this is true, but it makes an element of sense. I
personally use Prolon's spray and am sold on it. I pulled the Patent on it
a few years ago and seems it is based on a chemistry that was known in the
20's but was too corrosive to handle. What the Prolon guys did was to
stabilize it. They excelled to the extent that it is now an excellent
corrosion inhibitor.

I believe silicone sprays have their place as well.
