Yea, if I have to do that, I'm going to do it right. The shop will be replacing the dryer and evac'ing the system before refilling it for me. I *can* top off a system that's low, but this vehicle is a bit too nice for that kind of treatment. I want the right amount in there when all is said and done.

There is also a seal conditioner which would fix my leak assuming that the leak is between the evaporator and the expansion valve (they are both inside of a plastic housing under the dash). I'm doing some research to see if there are any harmful side effects to those.
