I can definitely recommend TGM in fleet. They have now dealt with a number of members from here (including me) and done a top job. They are not cheap however, but you get what you pay for.
I had my car keyed across 2 panels and they sorted it with a re-spray over the back arch and rear bumper. Whilst Wasso was detailing my car i asked him to watch out for any imperfections or identifying marks from the respray. He couldn't spot any difference which shows how good a job they do.
