Choosing Tile Repair Methods for Rentry

After seeing news about the latest foam-damage to Endeavor's heat
shield, there seems to be a problem in selecting one of three repair
methods.

Why not employ all three? Put in some foam; spray the dried foam with
heat-dissipating paint; then bolt on the plate.

Of course, even with all three fixes in place, the landing mission
should be "volunteer only" now.
Teacher-in-space gets to remain on station for another shuttle...or a
suyuz. What fun!
