Sorry to hear whats happened.
Shame your not closer to WSM, my neighbour round the corner is a paintsprayer and has all the kit for fairing repairs, from the work I have seen on bikes that he's done its pretty good.
There is a good sprayer in Bristol, in the same units as "Tim Blakemoor" who I would expect you to know.. I always forget the guys sirname but his name is Tim and he is very good, does bikes and bike related gear. Sure he can repair plastics as well.
Edit...
Followed Tim Blakemores site and found the info for you. Tims a good bloke and very helpful.
