Paul,
    Did he test it just on the prop or on the airfoils too?   In their
advertising they admit it is sometimes ineffective on props, but they'd have
you believe it always helps at least a little if you use it on the airfoils.
It sounds too good to be true.   Tom Mayer

I don't know as he is out of the country at the moment.

I would not be a bit surprised if it did help during that brief time at takeoff 
when the prop blade is stalled. It would probably be a drawback at all other
times.
