Park Tool ASC-1 Anti-Seize Compound

Ive been using this since I bought my first bike. Works on everything and I dont worry about seized bolts or cranks like ever

I bought this for my bikes, but I used to it on a squeaky car door hinge. It works great. It also works on bikes as intended.

What can you say about anti-seize? This stuff isn’t so great to get on you hands but if you put it on the threads of fittings being attached to titanium bicycles it works perfectly and stops them galling or binding.

Awesome Compound, it really does work. I will say its a lot for the price but since its 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. Ive 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 theyre 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!

More then I could use in my life. Worked as stated.

You must have this in your tool box. Use it all the time.

Works really well. Ordered this to lube all the threads putting together a new bicycle. The seat wouldn’t stop squeaking while I was riding, so I took it apart and lubed the assembly. No more squeak. Oh, and it’s also pretty important if you want to be able to maintain your bicycle beyond the initial assembly:)

Works as expected.

This stuff holds up much better than grease for any metal to metal contact where movement is not desired. Its closer to threadlock than grease, which is good. It prevents water infiltration, reduces creaking, and prevents things from getting stuck. I used to always use grease for everything, but I switched to using this stuff for pretty much everything except bearings and Im really happy with the results.

Good product. Works as expected. Would buy again.
