    The actual grease is pretty good but there are some problems I’ve had. First, this may sound like a first world problem, but you have to cut the end off which can be a pain. I ended up drilling out the end because I was having so many problems. Then, the second thing, was that the actual tube is not filled up all the way. There is a good amount of air inside the tube just like a bag of chips. You are expecting more then what your actually getting. Overall 3 stars for the problems but the actual paste is pretty good. Works great for what it’s meant for.

    Good stuff - an absolute must have for any serious do-it-yourself bike owner. But dont let the oversized tube fool you. As the description says, its 4 oz of product... but it comes in a 12 oz sized tube. A tube will still last years, but getting all the product out of it might be problematic. Great product - dumb packaging. That being said, its a great product that should be in every bike owners tool box.

    This rating is for Green Canyon Outfitters as much for the Park Tool anti-seize compound. In the process of shipping there was a snafu, but Green Canyon was super helpful and prompt in addressing the situation and made sure everything was right. They were a pleasure to deal with!

    Keeps dissimilar metals from fusing together. I used a light coating inside an aluminum seat post collar on a titanium frame.

    Essential for Ti and (maybe) Li Aluminum bikes!

    Necessary if you want to do the job right and avoid problems later as I prefer to do.

    This works great so far, I used it on my bike pedals. Took a little trial and error to get the right amount out of the tube
