By a company call hydro graffix based in Maidstone.
You have to post your parts to them and you'll have them back within a week. They do a variety of different options with the coatings and cf variations.
I'd really recommend having a look at the website and calling Adrian (the main man - details on the website) to discuss your requirements. I'm sure if you mention Gareth from the mk5 golf gti forum he'll sort you a discount.
I have no affiliation with the company at all. I wanted a gloss carbon look coating to freshen up my interior, so went onto google and found a place within 10 mins of my house. Took a chance, and imo it's paid off big time.
The standard of work imo is awesome, each piece has a perfect finish and it actually looks so much better in the flesh
