it looks like a very small area . I'd say keep it as a battle scar . my current car is safe so far but previous one was brand new and got a bigger rub than yours after just 2 months .. u stop acting about it after a while .
such is life on roads . you can spend 4k on this and some biker might rub another side another week. the trips to painter etc... it's non sustainable .
