a cracked windshield here is a fix it ticket if its longer than x inches. With the crater/star crack, the key is pressure to inject the resin into the crack, not just lay it in there.
When I was doing HVAC service (for the Lennox dealer) the boss was "big" on those repairs. There ways a local guy "Torgy" who did that. We had several of them done on the service trucks and none of them failed. I've no idea what that cost.
