They did my Superlight as a warranty job. Compared to the SC paint it is as tough as old boots. (The original paint rubbed off on my legs, leaving my calves with silver smears down them.)
I asked and paid for some extras such as lacquering the decals so they didn't peel off. They didn't do any of it but by the time I got the frame back I couldn't be bothered to pack it all up, post it back etc etc.
I went for the tough option as recommended when they heard it was for a mountain bike. After maybe 3 years it has plenty of dull spots, it doesn't clean up very well and is basically dull but…. the paint has stayed on, it isn't chipped and apart from one or two small "high wear" areas it has done its job.
Functionally then it is fine, aesthetically it is a little less successful. Me…. I'd o for functionality every time.
