Powder coating is fine - £66 was the cost - having said that, when I dropped it off I instructed the chap to only mask the brakes bosses and fork steerer. When I picked it up I immediately noticed the bottom bracket shell had been masked, which means the outer face of the BB shell is unpainted - and therefore a place where deterioration / rust can begin. I pointed this out and his reply was that this is how they do all the bikes. I won't be going back.
Regarding decals - I doubt the average Glaswegian drug addict is familiar with the Brodie brand! I will be ordering decals from GilM if I can afford them once the bike is finished.
