STP Auto Detailing

This is absolutely the best I have found. I have a tractor and the fan belt squeeks loudly. I, out of fustration sprayed the fan belt with "Son of a Gun" and the squeak disappeared. I ran out of the it and found I couldn't find it in any store in my area, as a matter of fact, anywhere I went. I found it here on Amazon and purchased it. I am happy that Amazon continues to offer it. I now stock pile at least 4 bottles. Back to the tractor, when I ran out of "Son of a Gun" I tried Armor-all, Belt-ease and other similar products, but the squeaks returned after a few hours. With "Son of a Gun" the squeaks go away for months on end. By the way, for the tractor buffs, YES, I replaced the fan belt with a new one, twice. The squeaks are on the belt, but disappear with this protectant. My tractor maintenance man, believes its due to one of the pulley wheels...costly to replace. He also recommended continue to use it.
