I have a rather big problem with water coming through my interior walls. I have discovered that the "stucco crew" either didn't know to flash around doors and windows or just didn't care. I am taking care of that myself but after ripping out a few walls from the sheetrock to the world outside I found that in a few places the house wrap was installed upside down and the top layer is in BEHIND the bottom layer. So obviously I have to find some way of water proofing the stucco so that there is no further seepage.

I am open to the roll/brush/spray on water proofers. But do they really last? This is something I will have to be sure to redo ever so often because if I wait until I see a problem I will have a major problem.

I have also seen some textured (cement based) products that are reported to be good waterproofers. The ones that I have seen are toweled or sprayed on. Do these last the longest?

Due to the design of the house there is plenty of ventilation for moisture in the house and so if I had to pass on the breath ability of my exterior walls I would be okay with that.

Any suggestions? Of course money is also an issue since this was supposed to be done correctly the first time and this is coming out of my lunch money. I would appreciate any insight you might have into this little fiasco.
