I would avoid the Wheel Specialist in East Kilbride, they damaged my tyres taking them off the wheels and let me drive home without saying a word, only for one of the rears to go flat 2 days later, when I phoned them to enquire 'Oh we knew we had damaged it but hoped we'd got away with it' They did reimburse for the tyre, but then a front went flat, again with a damaged bead.
The finish was never as good as I expected especially on close examination and the actually Powder Coating was brittle and did not take to the alloy properly.
I'm hoping for much better results when I pick my wheels up in a few weeks time from Colourworx in Dumfries.
