Just backing up ZZ re. Williams Powder Coating in Falkirk. I emailed Mr Williams to no response, but phoned and found him very pleasant and helpful. (His son looks after the website, and he doesn't spend any time on it himself.)
He doesn't do a mail order service, but is happy to receive a frame and/or forks by post as long as it is picked up afterwards, so I'll be sending mine down a couple of weeks before I next drive down to Embra, then get lost in Falkirk again, if it is anything like the hassle I had finding the Falkirk Wheel... I was quoted £40-50 for stripping and coating a f+f.
Also Velomaniac, did you get any joy from the powdercoater in Loanhead you mentioned? Is that at Bilston Glen?
