Aye Chippit,
If you care to PM me with your address, I'll send a CD copy of an original workshop manual down to you.
As for painting, I havn't done mine (Sally), but have done other motorcycles with both Hammerite, 2 pack enamel paint and powder coating.
Sand blast, 'Bondaprime' then 2 coats of brush applied Hammerite was cheap and durable. Chips were easily painted over and whilst the finish wasn't concours, it didn't look bad.
Sand blast then primer and 2 pack wasn't cheap, but very durable and applied by a good painter had a good finish, but not as good as coach enamel. Polishes up and keeps a good surface.
Sand blast then plastic coating wasn't that cheap, durable for so long and then begins to look tired ( won't polish up because of minute scratches). If worn through or chipped by a stone and then water gets underneath, the corrosion spreads unseen and may rot through the steel!

Conclusion, 2 pack or Hammerite for me.
Birmingham and it's environs should be able to supply all you need, when it comes to paint, upholstery, and maybe tanks.
Regards, Bill.
