AC "upgrade" warning

[James at ringsperformance.com]

Haudi,

In the interest of keeping good AC that was environmentally sound and worked
"like R12," Henry and I tried some Autofrost last year. The fine print
cryptically mentions what we discovered anecdotally: Autofrost leaks right
through R12 hoses, and Autofrost will likely lead to failure of your
compressor seal (GTI (Sanden?) and 4kq/York).

I have recently done the full conversion on the 200q and am so far happy
with the performance. I will post a full write up, including
cost/details/performance after an approaching road trip verifies happy cabin
occupants (37YO estrogen-based unit, 33YO testosterone-based, 4YO TB, 4MO
EB) for long periods.

Naturally, YMMV, but that's IME.
