> 3 dayA bit pricey, but at least I know what I’m getting. It’s Park so you know it works. When it comes to not wanting parts stuck on or seized up on your bike, it’s always best to use something you know works. I use this on my seat post, my shiny valve caps & everything in between that needs it. If you remember “a little goes a long way”, then this tube will also go a long way. For bike maintenance, I’d definitely recommend this product.

> 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 dayBought this to ensure that I can easily undo nuts/bolts in my new bike. These sellers are so cheap, the bike came without any grease at all and I farted all over just get the dang bottom bracket out.

> 3 dayI wouldnt think of installing a pedal without this stuff. If you work on bikes you owe it to your customers to take this small extra step so theyre not getting a hernia trying to get one of your pedals off in the far future. Mike Kirwan - Kenmore, WA

> 3 dayI had asked online forums and Amazon about the best grease to assemble bicycles, and this was it. Great stuff.

12-04-2025I purchased this thinking it had 4oz of compound and it’s mostly air inside the tube? Truly misleading. There’s actually just about 1oz of stuff inside. Update: I wrote parktool complaining about the quantity and they wrote back saying the tube didn’t fill up all the way and it’s defective. They asked me to return it to Amazon for a replacement.
