Pros: I just got my first "can" of Climb-On and it has helped me keep climbing when my hands can't go anymore. Sometimes your muscles aren't ready to stop, but your skin is torn up from rough holds...but you can easily apply it and use it as a second skin, before, during, or after you climb.

Other Thoughts: I you intend to keep climbing after applying Climb On, make sure you allow about ten minutes for drying time, or else you might slip off the rock.
