You have found one of the best sources for unbiased information on automotive air conditioning and engine cooling systems on the internet.
Cool Profits Magazine was the first journalistic source to write about Mercedes-Benz Antifreeze Anticorrosion Agent containing Glysantin G-05, and is an excellent source of information on all aspects of engine cooling and climate control. The magazine is published by John Hess out of his home in Petaluma, CA, and is directed towards professional radiator and AC shops.
I have had several conversations with John, and he is aware of MercedesShop, and the lengthy discussions we have had regarding Mercedes antifreeze vs "the green stuff".
Here's another example of why this resource is so great!
