The answer was a big NO! In zero gravity, as soon as we touched a tile, we found ourselves being pushed away. Without a suitably positioned restraint system, we could not work to fix the damage. We would have damaged more tiles than we fixed. I asked that we not haul the MMU on the STS-1 mission, because it could not have helped us do tile repairs.
