Visited my local Audi dealer to buy a pack of Estoril Blue touch up for my new S3 in case of any stone chips etc. They told me the touch up sticks are not available and this is now regarded as an exclusive colour. All they could give me was the paint code X5P. Has anyone else out there experienced the same problem? Chipex do a pack "guaranteed to be a 100% match for original paint" but I've never used it before and don't know if it's any good or not. Suggestions/solutions welcomed.
