Hey! Thanks for getting the MP Metal Protector chain lube. After you gave it to me it freed up the chain after 2 hrs of soak time. This chain was very stiff from lack of good quality perpetrator and lubricant your Ams Oil product proved to be superior to anything else used. My power tailgate on my tool truck now operates smooth and trouble free. Thanks for your support, your products continue to meet my expectations and, in this case, have surpassed that.
