And if you choose to cross the bridge at El Paso, Eagle Pass, Del Rio, Laredo, McAllen; Brownsville, be forewarned that alot of the so-called "R-12" they are selling down there is really R134A.

There are legit suppliers for R-12 on ths side of the river.

I would just as soon by Freeze-12 for < $10 a can knowing it's 80% R134A as to drive down yonder for somebody's version of who knows what.
