Review: It doesn't work, and then it does. - I recommend following the directions, but with a slight modification. When you first spray this on the belt (with the engine running), it will cause the belt to have a loud screeching/squeaking noise, which will be way worse than how it was before. I sprayed it on sparingly with the engine running until I felt the belt had a very light coating and the squeaking disappeared. After a day or so the squeaking would resume, and I'd do that process again. This continued for several times, until one day it just stopped squeaking. So I think the key is that it needs to be applied sparingly, but several times, and allowed to soak in. After a sufficient amount has soaked in, it seems to work. It kept me from having to buy a new belt, as my current one is in great shape but just squeaks. It doesn't last forever, though. I seem to recall it lasts about six or eight months, and then you have to spray it down again. It doesn't turn an old belt into a new belt, but it turns an old, dry, squeaky belt into an old, conditioned, quiet belt.
