Autofrost GHG-X8 announced for Spring 00. Now available from ATC Specialists, Inc as COOL TOPTM. COOL TOP is now out of production since modern R134a cars have better performance and the extra performance is no longer needed. Cooltop was intended for many of the poorly performing R134a cars of the '94-'98 period. Bobbie Burke has some remaining stock if you want to hoard some before it is gone.

See what happens when you use a chlorinated refrigerant (Autofrost/R-406A, R-12, Freeze12, HOTSHOT, etc) in PAG oil designed for R-134a only systems.
