penokee, I'm not sure what is the best substance to keep snow from sticking to your blade but PLEASE, to Theowegian and all others that have suggested using WD-40, DON'T. From an environmental point of view, you might as well go and pour another volatile organic compound like BTEX (gasoline) in your drinking water, because that's exactly where it will end up. I've spent over 25 years in the environmental business and I've seen petroleum distillates, such as TCE and BTEX, ruin entire water supplies. It's been estimated that one teaspoon of oil can contaminate over 400,000 gallons of water and make it unfit for human consumption. When you spray WD-40 on something and water washes it off, it doesn't just disappear, it ends up in surface and ground water where it can persist for a long, long time.
