Bill,

I have had the IV-P’= ;s prop de-ice on twice and was in ice once in 200 hrs.  I guess it wo= rked, as I had very light rime on the wings and windscreen.  I live in Arizona, so I don’t see ice like the North East and North West.&n= bsp; Many times I have thought installing the prop de-ice was a waste of ti= me and effort and then I think….if I “have to” descend th= ru ice in order to land, then I want it there.  Great debate item better served when I have a scotch and water in one hand.  I mak= e every effort to stay out of ice.
