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.
