This was easy to apply, worked great, no mess and almost no smell. The next day after running on the treadmill there was no odor and no feeling like the belt was sticking at all! In fact I noticed that it was sliding with me a little, which is a far cry from feeling like you're tripping when an old belt sticks. So if you're thinking of getting rid of an old treadmill or found an old one, give this a shot first and see if it helps. No complaints of any kind even after 4 months of treadmill use with only one application.
