Silicone spray I know incredibly well, but what's pam?
I've found that if I run at rated PTO speed the blower has yet to plug up.
I know that around here commercial coal truck drivers in the winter coat the beds of their trucks with kerosene or diesel. (They also do this with sand and gravel,some even use a vibrator.) This will help prevent the coal from sticking in the beds. When coal sticks in the bed, a truck can upset pretty easily. I could be wrong but if you were to coat your blades with diesel or kerosene,it may do just as good.
