Doofy - what the hey - it can't be so warm in Glennallen that the snow is sticking inside your blower. Normally, the cause of "sticking snow" is a substantial temperature difference between the outside snow and the temperature of your blower. Blower stored in warm shed - below zero outside = snow sticks everywhere in blower. OR - you are attempting to blow wet snow.
Answer to the first - move blower outside and let it get as cold as the snow before you use it.
Answer to the second - quit trying and wait until it gets colder outside.
I've only tried silicone spray once. It worked OK but didn't last very long. That's when I learned to quit trying to plow/blow wet snow.
