depending on where you are, the one around my area (warrington) is rage designs.
not cheap by a long way but will do what you ask and a superb job, they do alot of BSB, WSB and ducati work.
However if paying that sort of money, it may be worth considering getting an OE job done esp if you plan on ever selling the bike in the future.
a custom paintjob can make a bike very difficult to sell when bored with it. but i am sure you already know that.

I saw Big Stinks UK NC30 yesterday in the flesh. It's was featured in Practical Sportsbikes last year.
The paintwork is first class, it's in the RWB UK colour scheme. I couldn't fault it. A lot in Rhyl did it I think. If you search you'll find his thread on the rebuild. If I was doing mine, they'd be a worthy consideration.

RAPIER paintwork in Hull ,clive has been doing top quality paint jobs for over 20 years

me too , in leicester . been painting for years . gonna be a while but when my fzr engine sorted it going to be 90's marlborough yamaha colours . will post pics when its done later in the year

MOTOPAINT west mids , been doing my painting for years hes not cheap but good.

Any suggestions for those based in or around Surrey?

I think if u guys can gets pictuers up of the sprayers with their work it would clear things up I'm also looking for sprayers round Surrey!?

TBH you need to see work in the flesh so to speak, pictures hide a thousand horrors!

Really? :/

Used a company called Altamura for my repsol blade. Perfect finish and exact colour match unlike dream machine which was nothing like stock colour.
