Could anybody correct these three sentences for me?

Jolin Tsai's resistance to fattening food is extremely strong, so she can keep herself in good shape easily.
*I mean her ability to resist the seduction of fattening food is extremely strong.
Glass which resists shattering can be used to make glasses.
*I mean glass which won't break even fall on the floor.
Lucus is so brave that he dared to resist being robbed by that bandit.
*I mean Lucus is very brave and beat the bandit, when he tried to rob him.

Does glass countable?
I think glass is uncountable, when it is used to refer to general glass.
I used simple present tense (is), as Lucus is still brave and I use past tense(dared), as Lucus's resistance to the bandit happened before.

Many thanks in advance
