Does ES-12a leak like R-12?
Would it be beneficial to install barrier hose?
At $6 per can I might not care, but if it helps keep me on the road and out of the A/C shop it might be worth it....?
Thanks

One thing to remember. R-12 and ES-12 have molecules that are close to the same size. R-134 have molecules that are MUCH smaller.
This means that if there is any leak in the system and its not corrected, switching over to R-134 will result in your leaking out the coolant gas sooner than it would using either of the above gasses.
Even at $6 a can its worth not wasting (remember the earth we live on here guys) so if you have a leak try to find it then recharge the system. One of my cars has had ES-12 in it for 4 years now and still works excellent. Outlet temps were in the low 40's last time I checked.
