If it had zero pressure, after finding and fixing the leak(s) and replacing the accumulator, you really need to pull a vacuum on the system before recharging. NEVER use a stop leak in a AC system.
I had my mechanic check it out. They evacuated and recharged it. It was running cold but they said they detected a leak in the evaporator and kindly handed me a bill for ~$1100. They evacuated the system before sending it home with me so I didn't have to pay for their charge so before I filled it myslef it was empty.
The stuff I used says it has "3 ozs. of Lubricant including Cleaner, Leak Sealer & O-Ring Conditioner" So far, so good. Blowing cold on hot days.
