Only issue with these is they're on plastic trim? I would leave well alone and I don't think it'll have a colour code and will look worst.A couple of chip pics.
I've taken Andy 27168's advice and ordered some Chipex, watched the video and decided to go for it, gave the car a good wash today and found a few more , fortunately quite small, so hoping Chipex is the answer. We shall see. Thanks for all replies.
I do my touch ins with a rolled up bit of masking tape.
