Ooh nice is that paint or powdercoat or something else?
Re:
Yup, it is powdercoat. Good quality Austrian stuff:
Tiger Drylac 049/25002 Dormant Sparkle Copper with a gloss top coat. Colour Chart here.
There are plenty of lovely powdercoats out there.
Unfortunately, most of the companies who do powdercoat in this country are bogged down with cheaply painting girders and filing cabinets in greys and browns.
All the best,

Re:
Excellent work there.I love seeing frames most would consign to the bin being given a new lease of life.Ive never welded T6.Ive welded 7005 and that doesnt need retreatment after welding.How much furnace time/temp did you give your frame post welding?

Thankfully the Pace is 7005-T6 (or possibly 7020-T6, they just say 7000 series?), so only a light few hours at 180º to normalise things. 
A new build 7005 frame would get 8-10hrs at 180º, in line with Columbus and Dedacciai guidelines, or (allegedly) leave at room temperature for a month to age before using.
6061-T6 repair is a bigger matter, as any extra heat cycles from welding or ageing can over-treat the existing T6 condition metal making it brittle.
The proper full quench and re-ageing (525ºC +/-15º then quench down to T0 condition in water, align within 8 hours, age at 165-195º for 3-12 hours back to T6.) is expensive and risky to alignment etc with a lightweight structure such as a bike frame.
There are loads of variables, and should really be done on test pieces etc first, which just isn't possible with repairs.
