I just had my windshield repair about 5-inches long cracked on the bottom corner driver side. I recommend using Novus windshield repair. The cracked is slightly visible but he did an excellent job. He filled both end of the cracked to stop it from spreading. I used Novus for many years. Let me know if you need the number, if haven't done it yet.
You can pay it yourself and claim for reimbursement through your insurance. However, insurance doesn't allow windshield repair on cracked windshield, they recommend replacing it. If your cracked is on line of sight, I recommend replacing it.
