Give Allon white and Melvyn rutter a call and get a couple of ball park prices quoted, make sure you tell them its not an insurance claim and the job is a replacement rear wing and paint. Depending on where you are in Suffolk there is also Krazy horse and Richard Thorne.
Hapeth of tar and all that!
Funnily enough I'm off to Allon White's soon to have a couple of things done - I've always found them very reasonable. Thanks.
