A company who can spray a Polyurethane plastic part?

I have a plastic front panel bezel "surround" for a 12inch LCD display on a very expensive piece of test equipment we would like to spray as its yellowed badly with age (as Polyurethane does when its exposed to light) – its only a few years old - I guess that Polyurethane really is not that stable...

The display bezel is uncoated Polyurethane (PUR) with a slightly textured surface finish – this texture is nothing fancy just the textured “surface finish” from the plastic mould.

Does anyone know of a company in the UK or Europe who specialises in spraying small batches (single items) of plastic parts? Understandably the cost will be quite high for a single piece but I’m prepared to consider any reasonable quotation.

I'd like to have it sprayed HP / Agilent "Test Equipment" light Gray and I can send a colour sample, anything colour close will do – the current “Yellow” looks so bad….

I’m aware of this project / page, but I neither have the time, skill nor the ability to source the chemicals here in Czech Rep.

Anyone have any ideas?

Thanks - John
 
Local car bodyshop is who I would ask... Its normally just a plastic primer and go from there.
 
If it's small I'd go for an airbrush guy who paints bike/race helmets etc. Seriously talented people.
 
You might find that an application of a plastikote (?) paint does the job. If you cock up, it just peels off. There are youtube clips of it being doing to a SL1210!
 
I might just try the “RetrObrite”... what's the worst that could happen? did not the Kirsk Submarine Explode because Hydrogen Peroxide leaking from a bad wielded seam in a torpedo come in contact with water??? or am I mixing things up?

Anyone have working suggestions of handling Hydrogen Peroxide?
