NPG vs. Glycol Coolant - Opinions Please

[Dinger09]

My new Dewitts radiator has arrived and I will be pulling the old copper core system to put this beauty into my 61. I was thinking of switching from the traditional water & antifreeze to NPG from Evans and was hoping to get some feedback before I spend $30 a gallon for the stuff. I am also wondering if the stock water pump can be used. I will get in touch with Dewitts but am also looking for the tremendous practical knowledge of this forum. Thanks.

Forget the Evans stuff - it's "snake oil". Just use Zerex G-05 or equivalent - you should be able to get it at any decent auto parts store.
