Thinking about your question, wax paper is out as props are driven only by
friction. Wax paper would cut that friction.

The prop is clamped so tight that water just can't into the crack. Unless
you dunk it into a lake everything should be ok. Remember wood also
absorbs water. If you feel better about using a bond paper, be my guest. I
have heard people using pop can material as well.

What happens if you fly through rain? Wouldn't waxed paper or plastic
cut from a baggie be a bit more robust?

Newspaper shims work very well for wood props.
