I read some on it last year and it sounds great for race or other demanding applications. I bought four gallons of the NPG+, four gallons of the prep fluid, and the refractometer but then decided not to use it (so if you're interested we might be able to work something out).
It has many great features and does appear to be a top notch product and their web site has many interesting articles. I decided not to use it because of a couple perceived/heard things about it in passenger vehicles: it does get thicker when cold and on some vehicles it results in lower heater output. It also has lower heat transfer than the normal water/antifreeze mix. In some vehicles in cold weather it can cause the engine to run fairly hot at idle. You can't have hardly any water in the system (like in the 1-3% range I think it was) and it will absorb water from air if system isn't sealed up well or for whatever reason it sucks it in the water pump weep hole or rad cap.

I use it in 4 of my personal vehicles with great results.
1991 Tarus SHO
1988 F-250 diesel
1993 Tarus SHO ATX, track only vehicle
1969 Ranchero 370+ RWHP N/A
the only vehicle that gets hot is my
truck when towing 60+ mph, gauge swings
all the way over in the red if im into a
headwind but I believe it is normal, during
cruise at 70mph gauge is pegged hot but any
decrease in mph or coming to a stop it cools
off quickly, and towing in city the engine is reading normal
temp readings.
all the cars run with normal temp readings, even the track car after 30 laps at Sebring Int raceway, 7 psi cap on all 4 cars.
so I am confident this product keeps me from less cooling failures than using conventional coolant.
basically pour in maintenance free lifetime coolant and
treat the engine to the new tune
enjoy
