That site works, I didn't see any R12 stop leak so I sent them an email.
Anymore tips appreciated.

Wow, they did just about a year or two ago! I guess the market for R-12
"secondary" products is really drying up fast, too.

No ideas on sealants here- if it leaks, I fix it rather than goop it anyway.

Most likely because they plug up recovery equipment.

Look for a product called Quest R12/R22 Super Seal  (do a google search).

NAPA stores also have an R12 leak stopper kit, can't remember the brand.

NAPA no longer carries R12 sealer, but I'll google for Quest.
tnx

Steve's advice was sound: Fix the leak instead of gooping it up.

How are those sealers supposed to work without affecting things like
expansion valves, orfice tubes, and piston seals?  I once talked a
neighbor out of switching from R-12 to a legal drop-in replacement that
included a non-curing silicone rubber sealant. I told him it would be
better to replace the metal-metal hose connectors on the condenser.

By reacting only with air. That's why they're only effective and
non-damaging when installed in systems that have been completely evacuated
and had a new filter-dryer installed. Otherwise they just make an
expensive mess. And in most cases, as long as you're going to evacuate the
system, you may as well just fix the leak properly.

There is no such thing as a "legal drop-in replacement" refrigerant.
