Antifreeze OUTLANDISH idea.......

[SuffolkD at aol.com]

Ti as usual, knows the Pentosin antifreeze is Blue.  I confirmed that the $17 
Audi dealer stuff is blue.  (Not green)

Similarly, the $9 Cryo-tek stuff at Home Depot in the heating cooling isle is 
the same color..........(used to be red AFAIK)

Since the hydronic boiler has cast iron, copper and maybe alumnium parts in 
it..anyone ever look into the cross possibilities that this stuff may be 
compatible?

Thinking out loud............
