Well I know it is leaking at 2 spokes, the guys are extremely experienced as they do wire wheels on lots of cars over the years. The black seal on the wheel in question was in pretty poor condition and very patchy compared with the spares sealant they put the tyre on this afternoon. They have a special sealant which they are leaving overnight to cure and see if it does the job, I know it worked immediately and sealed one spoke. If worst comes to it I'll get the MWS sealant and they will sort it out for me .
Thanks for all the input.
