i touched up some stone chips on my bonnet and wing, put some 'kurust' on (1 or 2 had a tiny dot of rust which i didnt want getting any worse then got the 3 pen touch up kit from halfords (about a tenner), works all good if you take your time between each pen but the colour match (quarts silver) is terrible, thankfully becuase there only like 3 or 4 small chips i did you cant actually notice it until you look at it, but looking at it close the colour doesnt match, better that than having the black/rust colour on the chip though
