I picked up a kit of Blaze anti-fog from the Greeneville motorcycle show, which included small spray bottle, couple small paste cans, etc. Was a pretty impressive display they had set up demo'ing the product. However, I used it on my helmet visor, and can't seem to tell it makes any difference at all...especially on the morning commute, the inside of my visor still seems to fog up. Has anybody else used this product with success? Am I doing something wrong ?
