    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!

    anti cease compound do not use as grease, not for moving parts, stationary threads only. Park tool makes a good grease if that is what you need on moving parts.

    I like the squeeze tube. Less mess for my applications. The product squeezes out in a controlled manner. It applies like other anti seize compounds I’ve used. It’s higher price is one reservation that I have.

    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.

    Works great for steel bolts in alloy parts. Would be nice if a smaller tube was available. A little is all you need.
