Altho my front, passenger side one cud do with a refurb after an incident of a lorry cutting a corner and me having to pull really tight into the mud bank at the side, which happened to be full of stones
To get a paint match you could try a car paint suppliers, just take your petrol flap off and take it with you and ask them to colour match it. Or you could take it in halfords aswell and ask them to colour match it.
