Minor scrape - insurance claim?

[red_slr]

Mrs SLR driving to work today in the nearside lane and a car in lane 2 squeezed her over when moving over into her lane. Very minor contact caused scuff to bumper. Neither party stopped as it was not clear that there had been contact (mrs was sounding her horn at the point of contact). Luckily dash cam caught the incident and VRM of other vehicle.

Looking at the scuff its probably a smart repair but as the car is new it might be best to put into dealer to maintain the 10 year paint warranty.

However, if Mrs SLR goes to her insurance will this be a claim on her records? Given she has 18 years no claims (protected) is it worth it?

As the other party did not stop there is not really any other option its either pay for it ourselves or insurance.
