Recently got a 99 clio phase 1 and had a rust issue which I've fixed up but after going to Halfords for the paint Mv671 they said there was 6 shades, after looking around I found no help so just thought I'd chance it and got what they said wad their 'standard' shade and it was miles out when I sprayed it up, anyone know how I could find the specific shade of my car or any ideas of where to get a closer match?
