Will they waive my deductable - rock chip on winshield ?

Did you call LYNX? It's probably a service they have a contract with to take care of this. It will depend on policy as to what they can and can't do. So you need to call the number they gave you or call them back and ask. There is no way anyone here could answer this for YOU as we don't have ANY WAY to know what is and is not in your policy unless you tell us (and that would not be such a good idea).
