I wouldn't bring a car to the insurance recommended repair shop, they are often the cheapest (for insurance) and lowest work quality. My dad had a trunk replaced at insurance recommended Carstar from a rear end and it leaked water in the winter (Also poor paint quality finish, overspray, orange peel texture) . He brought it back multiple times and it was never fixed, honestly wouldn't be surprised if they just left it in the lot for 4 hours and didn't do anything to it at all. In the end had to fix himself.
Instead bring it to dealership bodyshop or manufacturer certified bodyshop. I had another rear end that was way more severe, almost 10k in damage. It was repaired at dealership bodyshop with OEM parts, never had a problem afterwards 8 years later.
The insurance "lifetime guarantee if brought to our recommended shops" is a trick because the shop that you bring it to will warranty the repairs anyways.
