I would get one of these repair kits off Amazon :- https://www.amazon.co.uk/gp/product/B07K27667J/ref=ppx_yo_dt_b_asin_title_o09__o00_s00?ie=UTF8&psc=1 I had numerous very small chips which would glint when the sun caught them. I wasn't very hopeful given the price but it worked really well and now they can hardly be seen. Took a long time to come all the way from China but I will get another one when the filler runs out. H
