Hello, one or the other may already know me. My mother has n Renault Megane, pretty fancy car, but n “AUtomatics” *bäH* nya theme is, she has light kratzer on the bonnet, which looks like someone put a plastic box off and pulled it once, so that there are 2 cm long and 10-15 cm wide scratches! How can I get them out there again, does that work ?
