Gun Oil Corrosion Test – Lucas Gun Oil

Lucas Gun Oil is a well know lubricant and particularly more famous in the automotive industry but anyway let’s see how well a straight gun oil prevents corrosion.

I use a simple corrosion test which entails applying a gun oil or CLP to a clean bare metal plate. I spray the treated metal plate with water and then let it sit outside in the desert climate until rust appears. Every other day I will spray the treated plate with water until it rusts.

Here it is…Lucas Gun Oil

Here’s the gun oil corrosion test setup….clean metal plate and Lucas Gun Oil.

Here’s the steel plate. Nice and clean and no rust.

I apply 2 drops of Lucas Gun Oil to the steel plate and then I’ll spread it evenly.

Closeup of the 2 drops of oil. Lucas Gun Oil looks just like motor oil unlike other gun oils and CLPs.

Now that the Lucas Gun Oil has been applied, I can start the test with a good spray of water.

I gave the test plate 2 good squirts of water.

It’s a little hard to see the water because it did not bead up. You can see a few beads in the lower right hand corner. Now let’s see what happens in the next 24 hours.

24 Hours Later – Lucas Gun Oil Corrosion Test

There is a light film of rust taking hold. Let’s take a closer look.

RUST….Lucas Gun Oil does not provide a long lasting corrosion barrier but it’s not a CLP either. Lucas Gun Oil is a just a lubricant.

Archoil AR4200 CLP Corrosion Test

I have used Archoil AR4200 CLP in the past and was happy with the way it performed on my Glock 22. Let’s see how well it Protects bare metal against corrosion.

I use a simple corrosion test consisting of a piece of bare steel, gun oil or CLP, gun cleaner, cleaning patches and a water spray bottle. This is an extreme corrosion test and most firearms will never be subjected to these type conditions. But it will show what gun oil or CLP is absolutely the BEST at protected metal against corrosion..

Here’s the setup. I cleaned the steel plate with Mil-Comm MC25 gun cleaner first. It’s squeaky clean.

Here’s the high tech CLP from Archoil. It’s a super lubricant. It says “Superior Corrosion Protection” right on the bottle.

I put 2 drop of the AR4200 CLP on the metal test plate. I’ll spread it evenly with a few patches.

The steel plate is now evenly coated with Archoil CLP. You can see that it removed a small amount of dirt from the plate.

Now it’s ready for the water spray. You can see the water beaded up on the metal. Let’s take a closer look.

It certainly looks protected with a thin film. Let’s wait and see how long the protective barrier lasts. I leave the test samples oudoors where the temperature ranges from 55 – 95 degrees F. I spray the treated metal every 48 hours and stop the test when rust appears.

Day 2 – Gun Oil Corrosion Test – Archoil AR4200 CLP

Looks like rust to me. 48 hours + water is the limit for corrosion protection from Archoil AR4200 CLP.
