I don't mean to sound disrespectfull, but what makes you think that if you put some tape on cracks that the cracks will not come back?
If the wall moves it's gonna move. Tape or no tape.
I have patched over so many taped cracks that you could not imagine because people are led to believe this.
Even if you apply fiberglass, the crack is going to come back again if the cracks are dynamic.
All the tape does is make it three times harder to repair the next time.
