I've had my Pescaras refurbed!
Had a tip off from a trade buddy about a place in NW London, West Hampstead to be precise.
http://www.fawheels.co.ukWent to their yard, had my wheels off and a loaner set on in 20 minutes but very careful with my spacers and wheel nuts and I had a wide choice of finish and colour to choose from. I watched the guy Jacob test my rims for trueness and all were good. The turnaround time was 3 days and I'm very happy with the results. Pics to follow.
Thanks for everyone's advise - this place happens to be on my way over to my folks and having spare rims was the clincher.
