powder coater recommendations for Leics, Nottm, Derby?

[Leatherseat]

NB- Double post, also in The East Mids section.

Has anyone used a powder coater for a frame/ forks in or near Leicestershire (or up to Nottingham or Derby) they would recommend? :?:

I know there are some scary tales, others have good experiences. eg Are the threads blanked off /cleaned afterwards?

Thanks in advance,

David
