Decided to go with chipex. Will post some pics of before and after when I get around to doing it.
Be interested to see before and after pics as iv just ordered the chipex system for my Carbon Grey
Have you not tried the dealers for the official VW stuff? I've even seen it on eBay - https://www.ebay.ie/itm/161939268879 The brush that comes with it is too heavy for a small chip but you can use your own brush or a cocktail stick. I wouldn't bother with the lacquer either. Chipex is comically over priced and it's claims re usage / miracle cures are dubious to say the least.
I would complain to Chipex that the colour match is terrible if I was you, you'll probably get another bottle of paint or a refund, in my experience they have excellent customer service.
I used to be a parts manager and the amount of times people came back saying it was a poor match.Shake the bottle for ages and try again!
