Mobile Scratch Repairs

[mike n helen]

Managed to scratch the bumper on the wife's car at the weekend, which was quite annoying as the parking sensor warned me about the plant pot which had jumped out behind the car.......

Can anybody recommend a mobile repairer in the Washington area, there's the obvious Chips-away but would rather go on somebodies recommendation than just pick the best known. Also any idea what it cost for a repair for a scratch about the size of 50p piece?

Thanks.
