[Gmcnet] Duracool compatibility

[jesse farr]

All shampoo manufacturers say you have to wash twice where can sell twice as 
much shampoo, too. That might have something to do with it. And, it probably 
would be better to have all more efficient coolant; but, it is much easier 
to simply add a can every year and then after a couple of (well, several 
anyway) years, you probably are all 12a, anyway. <g>

Actually Emory the Duracool site  says that the existing refrigerant
must be removed before charging with Duracool.

See Below:

To replace CFC-12 with DURACOOL 12a® requires the removal of all
existing refrigerant.
