Glissandos in Waldstein

[MasterTuner]

 This is my first post so I would like to say hello to everyone.

 I am very interested in playing the Waldstein but, I don't know how to go about playing those octave glissandos in the last movement smoothly.  Could anyone give me some advice?  That section is the only part of the piece that scares me.

Well, you could do what Serkin did and stick your fifth finger and thumb up your nose for...lubrication before this passage.
