compound polish - removes a layer of paint and reveals a fresh layer which is free from swirl marks .. also used to rectify small scratches which havn't completely ripped through the paint
cutting cream , not sure , but probably used by dentors to remove paint from car
wax for black cars - i use turtle wax hard shell wax and am very satisfied - if your car is old and paint lacks in beauty due to swirl marks and fading , use turtle wax color magic (black) . it will restore shine .. it will cost u rs700 and [I]black box will cost u around rs2000
[/I]as far as the residue is concerned , that is dried out wax .. use a microfiber cloth to wax and clean the edges of doors , bonnet , fuel lid , lights and other trim items properly
