Good stuff and good sized tube.
Does the job. A must application for titanium bike builds and parts. I run titanium stems on three road bikes and without this stuff applied it was difficult to get clamp bolts tight enough to hold bars from rotating. Coated the stem bolt threads and inside of threaded stem areas and everything snugged right up without and creaky protest. Generous sized tube will last a long time. Also much better dispenser vs. small packets from other brands that don’t reseal and dry up.

A must have for bottom brackets!
I have several greases, many from Park Tool which I use all for my two bicycles. Recently needed to change my DUB bottom bracket and found this particular grease. Goes on easily, based upon many internet review this is ideally suited for the task!

Awesome Bottom Bracket and grease Compound for threads on the Market!
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!

Ok
Compound separates after sitting a while. You have to knead the tube before using it. Still has just oil in head of tube you have to squeeze out first.

Great for BB fitment.
Worked perfectly with a Wheels Manufacturing BB into a carbon press fit BB.

Nice!
not much to say, works as it should... less messy than one of the bottles with the brush

Better than the green one!
This stuff works great. Its particles increase friction, and your torque levels significantly decrease because of it so you don't over-tighten your bolts. I probably use this more than my standard green grease, but it this has it's 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.
