As I said Joe, it must be done correctly. When a proper repair is made (via patch), a low viscosity rubber compound is injected into the hole before the patch is installed. This rubber cures rather rapidly, and is thick enough not to just fall out. It is also what keeps the tire sealed from the outside. Each person is definitly entitled to his or her own opinion, but as I mentioned, you may want to talk to someone that REALLY knows tires (ie. Michelin rep) to get the straight scoop.
: When a patch is applied to the inside of a tire,it does not keep water from entering the hole that the projectile made. Water will enter there since tires are not self sealing and can rust the belts. I would rather use a plug which seals the hole than leave the hole open to the environment. I really don't put much credence in your wicking theory and even if it is correct, I think less water will enter than if the hole is not plugged.
