On my drivers door i have about 6 patches of surface rust, each are about the size of a 50p coin, its very lightly surface, and all but one patch are bellow the bump strip, if i sand it back and prime it, am i better to spray the patches or to spray the whole door? becuase they are spread out im worried it will look bad if i spray patches, its a mk3 dark blue/purple 1997, the rest of the paint work is in excelent condition. Any thoughts or tips would be greatly appriciated, i will post pictures tomo on this thread when its not dark!
thanks
