    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!

    Its been a couple months so I have no idea if its working - 5 stars! (I trust it is. This review will quickly change to 1 star if something seizes, though.)
