[C320-list] Club Racing the C320

Tue Aug 28 19:10:06 PDT 2007

Hi Mike
I would appreciate hearing from you as to how your PropSpeed has lasted.
BTW did you know you have to remove all of the Pspeed prior to re applying a 
new coat?
Our experience is 12 mths +
When you say the cost of PropSpeed is so expensive ... are you buying the 
Pspeed or having someone else do it?
