I believe they spray all Sigma, Geoffrey Butler, Chas Roberts, Shorters frames and also do specialist in airbrush work.
I was going to get my frame sprayed with them last year but never went through with it so cant personally recommend, but i have heard good things about them.
I think the quote they gave me was around the £100 mark for enamel and cc.. this may have changed.
