Stuart,
I don't know how urgent you need the work done but I'm looking to get my wheels fully stripped and re-sprayed in next couple of weeks in line with new tyres.
I've had a third hand recommendation off a mate and will be giving them a go unless I get a better alternative.
I'll post the results none the less. I know there are a few top quality sprayers and mechanics/engineers in the south Wales area, they just need to be coaxed out into the light.
I'd be interested to hear of your experience if you get yours done in the mean time.
Good luck,
Ru.
