Got a very prompt and detailed reply from Derwent. Including pretreatment they charge £40 as long as the colour I choose is in their range, if not it's an extra £65
I'd really like to use them if possible as I've checked them out on a map and they're literally down the road from me. 5 or 10 minutes on my bike. It would certainly save all the postage hassle. Obviously depends on a couple of things though, I'm yet to find out if they have ral 5011 and I want to see the quality of their work before I have it done. Failing this I may just take Lewis up on his offer.
Legacy: How good is "good"? Any orange peel or is it a real smooth finish?
No rush with all this though, I haven't even bought the frame yet and I want to ride it for a month or so to make sure I like it before I start throwing money at it. Got to get it modified by Mercian too. Just want to have a really good daily beater for a change.
Photos will come up here afterwards of course.
