I haven't seen anything recent about this product; anyone using and have an opinion?

From what I can gather, seems like it works pretty well depending on prep and application.

Benefits: no water = lower corrosion, no pressure due to higher boiling point = easier on the system and no pressurized leaks, no silicates = easier on the water pump

Cons: expense (but really not that bad when factoring longer term benefits), potential higher operating temps if not enough cooling capacity (guessing), might cause leaks if gaskets are porous.

Flammability - doesn't seem to be an real issue compared to other antifreezes.

Conversion - not easy to get all the water out - can have up to 3% water - gonna use in a new, dry block so not an issue for me.
