R12 substitute is available at most auto parts stores and Wal-Mart.

I wouldn't use stop leak because I don't know what's in it and if it can cause problems down the road. If it takes 2 years for the freon to leak out to the point that you need a recharge I wouldn't start throwing money at it until I absolutely have to. I'm just cheap is all.

R12 substitutes are fine, but you might have to, um... arrange for an accidental discharge before you take it in for a/c work. Some shops see the substitutes as contaminated freon.
