So as the tittle says it when the car went in maintenance someone at the garage seemed to spilled a drop of oil (looks brown yellow ish) i think on the paintwork and it dried off i have cleaned the car then used bug and tar remover .. no result then i used meguairs clay bar ... no result my Q was can i maybe get it of with Meguairs scratch X 1.0 or will that worsen it ... anyone got ideas ??
