Some good time could be spent checking out very good information regarding
vehicle, mobile A/C refrigerants on the MACS site and EPA site (Google).

You will find that R12 can still be sold and used in the USA. R134 can still
be used also. R134 is not banned, is still in production but is just not
desireable and will soon be obsolete. There are recent represented
production capacity problems ( I see as real and manufactured) with R134A .
Check the sites. These sites have the best FACTS available.

No doubt, there are sources for recycled R12. We stock, sell and can still
readily purchase VIRGIN R12.

We recycle R12 on site as professional shops must do and then use the
recycled product for leak testing systems that come in 'flat'. We then
remove the test charge R12 back into our recycler. And, as side information,
a good on site recycler will provide clean, dry, 100%  useable R12  that
some have tested and found to have less non combustible gas (air) than some
virgin products. And, before we tackle refrigeration system repairs in our
shop we must test the refrigerant in the system to make sure that what's in
there is only R12 or only R134A and not a blend.

Technical data will support that R12 is a very good refrigerant for mobile
systems. Performance claims made by manufacturers/marketers of blend
products do not stand up under technical scrutiny. This can be checked out
on MACS site. There are many reasons why we do not support the use of blends
but one outstanding reason would be that  blend constituants bleed off (leak
out) at different rates leaving a system with some strange concoction in it.
Some have propane and butane which can go poof! Even R134A is explosive when
mixed with appropriate amount of air under pressure.

Personally, I feel the whole Montreal Protocol implementation program has
many serious faults. Doesn't matter what I think however, so I either step
up to the program or step out and so far we have been staying with the
program and continue to spend many dollars buying new equipment in order to
stay with it.
