> 3 dayGood product works as described. Used for my titanium pedals and for the cleat screws on my cycling shoes. Both require use of an anti sieze product.

> 3 dayThis stuff works great. Its particles increase friction, and your torque levels significantly decrease because of it so you dont over-tighten your bolts. I probably use this more than my standard green grease, but it this has its specific uses and blue is my favorite color so I’m biased. If you have high quality aluminum, titanium, or carbon components, this compound is fantastic. Highly recommend having this in your tool box, junk drawer, bicycle fanny pack (you do you). This is for sure an essential item now that I have bought it and determined it as such.

> 3 dayUsed for pretty much any metal on metal on my bike rebuild. When I have to change or remove anything the screws come out like butter I highly recommend this product for any bolt you are concerned you may need to remove later on.
