Silicone will break down over time, and quickly with the heat temperature of the engine and the sun on the hood of a car. Even with cold and freezing temperatures silicon is not a good choice. It will just fail and fall off leaving the metal exposed. If you read the label on silicon, it suggests that you don't use it in extreme temperature conditions.
