A & C Shotblasting.

I powdercoat just about everything these days. My bikes are meant as every day transport rather than show machines & powder's so much more hard wearing than paint or chrome. Cheap too. A full trike frame, shotblasted & coated is 80 to 100 quid depending on size.
These guys are industrial coaters really but turn out a pretty good finish for normal road use. They can blast anything up to a small car chassis size & have coated several trike frames for me.
Fast, reliable & cheap. tell 'em I sent you!
