@ Gathinga,you dint explain what kind of scratches they were or what caused them.
Otherwise if they are the minor kind caused by your car keys,shrubs (e.g. the kind you sustain when you drive through bushes,game drive or after a visit to an unkempt shags),don't waste your money looking for someone to do it for you.
Walk into Nakumatt,motor accesories sections and pick a tin of Turtle Wax ( Kshs. 345 for a small tin),and the color restorer. Also pick a face towel of about Kshs. 80 bob.
Then on saturday morning or sunday morning,wash your car and then using the face towel apply the wax over the areas with the light marks,leave for about ten minutes and then rub away the marks. do the rubbing in a circular motion. after that you can wash your car,apply the color restorer (about 750bob for an aerosol bottle),and then apply another thin layer of wax evenly. This should sort you out and will give your car a sparkling apperance especially if it's pearl white or just white.
