I saw a youtube of a guy extolling the virtues of soaking your serpentine belt in 303 Protectant before installation. He had a belt with 300,000 miles from a car that still showed no cracks on the inner ribs. He also highly recommended it for tires (inside and out) to prolong the life of the rubber. I have heard that Armor All is not recommended by some detailers because it is petroleum based but a few years ago they changed the formulation to a water-based formula similar to 303. I'm interested in thoughts from my fellow Gurus on this.....
