How much NPG+ do you need for your coolant system?  We just pulled the Eagle off of Ted's airplane and he has given me the NPG+ that was removed.  If you'd like to do the testing I can save you some money, I know Evans gets $22.50/g or so for the product.  I'll send you enough for your coolant system for the cost of packaging and shipping (from zipcode 32751).  Let me know.  The stuff only has about 4 hours on it, looks like new.
