I had my Curtlo coated there. They did a good job but not an amazing job. There were a couple of lumpy bits, some gritty bits round the dropouts, and a pronounced "scar" where they hung it on a looped wire, despite a plethora of threaded holes that might have been more appropriate. It took 2 weeks (the previous powdercoat was too tough for their blaster so it spent a week in the dip) and cost £60 which ain't too bad for Surrey; half the price that the Bordon place wanted!
They are new to bikes though, having done more in the last 6 months than in the previous 15 years...
