Blow proof bells

I dont run the starter cover or the Boot for the shift fork. Trying to keep the clutch cooler. I will never drive the car in the rain so no need for it. JMO

is that what that boot is for on the shift fork? i always thought it was just for dust, never thought it would be for rain too (doh!)...i do plan on driving mine in the rain if i get caught in it and im not running the boot...is my pressure plate/disc/flywheel going to rust out if i do?
