    Awesome Compound, it really does work. I will say it’s a lot for the price but since it’s made in America you get what you pay for. It will last me a long time, as long as you use it in small amounts, it wasn’t just perfect for my bottom bracket, but Threaded surfaces like limit screws, axles, cone nuts, axle nuts, threaded spacers, etc. I’ve used this on Limit screws, my Bottom Bracket, any place with a machined threaded surface, hole etc. In fact on my bottom bracket shell of my frame was threaded, I did put ASC-1 grease on the threads inside the shell before installing the Bottom Bracket. The biggest problem I have had is the stripping of the threads, which is my biggest problem, so I started using it on screws on my derailleurs including my freewheel, and anything and everything with a threaded surface going into metal parts. This stuff really is awesome, and Park Tool is a brand and company I trust completely they really do know what they’re doing. My only Recommendation to Park Tool is to put this in a tub like they have with PPL-1. Otherwise if you go through a lot of this you have to be prepared to spend a lot. Otherwise, I highly recommend it!

    The alloy seat post on my steel frame bike was slipping with my usual lithium grease. This assembly paste from Park Tool sorted the problem. Highly recommend.

    Nicely packaged and more convenient to use than the brush that usually comes with aluminum antisieze. Will be using this from now on just for convenience and not having to slam bottle on counter to get antisieze back down on the bottles I usually use. A++

    Bought a Thudbuster LT seat post and needed to clean and lube the shaft. Since I have a titanium frame, I did some research on different lubricants. Ultimately, I erred on the side of caution and opted for this particular lube specifically because it is anti-seize. It’s easy to use and the new seat post slid in easily as well. It is a bit on the expensive side in terms of lubricants but the peace of mind is worth it when you invest a lot in your bike parts and want them to last. The size is also great for storing in a bike pouch along with some other small bike tools. I only applied this a month ago so I cannot speak for long-term efficacy. Thus, the four star rating for now. If it still holds up after some time, I will up the rating to 5.

    I used this Park grease on my titanium frame for the headset and bottom bracket install.
    It works as advertised and I’m impressed with how easy it made the job.
    Be sure to use rubber gloves because this is serious grease.
