Its called prestige panel care, they are based in scaynes hill RH16.
The owner is trevor wilson who is a mini enthusiast and owns minikraft I believe. They were really helpful and did a perfect job when I had some rectification work done on my Leon Cupra R a few years ago.
They are a smaller repairer, however I've found that its these garages that do a better job as they rely on word of mouth.
Good luck
