Hi Adrian, good luck with winning your case. I'll see you this Sunday at the event. I can recommend Specialised Paintwork (
http://www.specialisedpaintwork.com). They are not cheap, but they do not cut corners with quality. Call reception and talk to Carl. They are based in Western Reading near M4 junction 12. I painted both bumpers, wing and driver door there. To cut costs I took 2 days vacation from work and did all the disassembly/assembly work at their premises so that they basically took parts from my hands and painted them.
