I used place In Barnsley called Metal Magik they are just of the M1, they actually refurb alloy wheels mainly, any place like that should do it fo you, I know a freind in Leicester uses a place just off the M1 aswell nearby to hmself.
also - it cost me less to have it pwdercoated than it did for respray,
heres a picture of one of the Aero Table I also got powdercoated.
the first Aero Table I did was also a respray, the 2nd one I had to go for powdercoating, seriously its just so much better

incase your wondering, I've resprayed a few cabs, and powdercoated 2, if I need to do anymore its powdercoating all the way unless I want some rel funky colour (which I doubt)
