Does sound miraculous.

If I remember right, that one is like %80 r-134a.

With r-12 now around $25 per pound, all of these alternative refrigerants are looking fairly silly.

Now, compare $50-60 worth of refrigerant to the cost of a new compressor, or any other AC component, for that matter...

Freezone is around $17 per pound. How much are you saving?
%80 r-134a. Nice profit margin! How much does that 142b cost them?
Not only that, this one still requires a 609 license to purchase!

The more you dig into the vast array of miraculous alternatives, the less appealing they become.
