Renault do not do one due to such little demand. Halfords will mix you one which is as near as you can get. I gave in and parted with a lot of money to have the full side of the car resprayed to a very high standard. LY is almost impossible to match in small areas.
Had a reply to a query email from Auto paints st helens.
They said they can do ly at £4.95 for 40ml and that it needs a groundcoat (u/c 1203). Assume it is the sam price for the ground coat.
At this price I mite just give it a whirl.
