I tested a few CLP’s over the weekend and one of them was Otis Bio CLP. The test was a metal wear test where 2 pieces of metal are lubricated and then slid against each other like the action of a gun. The surfaces are polished before the test and then inspected after the test to determine how much wear resulted. I use 6061-T6 aluminum alloy for this test because it shows wear much faster than the harder steel alloys.

Here is the setup. The base is a .5″ x 4″ x 24″ extrusion of 6061-T6 aluminum alloy. The sled is another piece of 6061 with dimensions of 1″ x 4″ x 6″.

The surfaces of the aluminum alloy are polished with 400 grit sandpaper.

Both surfaces are lubricated with the test oil/CLP. A very thin film is all that is needed. Then the smaller block or sled is slid back and forth on top of the larger bar. 75 cycles are performed. One cycle is one forward and back motion.

Here is the sled after the test. Very little wear and I knew this before the test was completed. When I was performing this test, I could feel how slippery the Bio CLP was. It’s great stuff! Let’s clean it off and see how much wear there is.

Here’s a close up of one side of the sled with very little wear.

Here’s the other end. You can see a little wear.

Conclusion: Otis Bio CLP is a fantastic lubricant. It is very slippery, much better than most gun oils or CLP’s. Bio CLP also cleans very well and doesn’t smell. If you want to give this stuff a try, here is a link to buy it online….Otis Bio CLP at Amazon.com
