Armor Regeneration Question

[Loser]

From Fyron's Modding Tutorial
Armor Regeneration
Value1 = The amount of structure points regenerated per combat turn.
Value2 =
Valid in Components.txt, VehicleSize.txt

Having this ability with Value1 at least 1 allows the component to regenerate in combat. All of the regeneration abilities for all components with this ability is added up, and this many hit points of damage to such components can be repaired each combat turn. After combat, all components with this ability will be repaired.

About this ability:

If this ability is given to a Component, or to all Components, with a Value1 of zero, will those Components, no matter how damaged, be fully repaired after battle?

If a whole ship was made out of this stuff, would complete destruction be the only way to actually stop it?
