Some kind person has run a key down my door/rear quarter just had a quote to get it done and it came back at £1400.
Obviously I know you get what you pay for when getting cars painted and that liquid yellow is a pain, But that seems a bit excessive.
If you can't find anywhere local then Westover accident centre in Poole (not a million miles away) did a flawless match on my LY boot when it went in under warrantry for corrosion. They are the factory approved centre for the Westover franchise of main dealership's which includes Renault etc.
