A complete waste of money spend a couple of hours using a good quality car polish and some elbow action and you can get a better protection on your car and the satisfaction that it’s done properly get good polish pads to put the stuff on and good microfibre cloths to get a great finish I always wash/dry my car and apply a Mequires polish to finish the car off best of luck👍🏴󠁧󠁢󠁳󠁣󠁴󠁿🏴󠁧󠁢󠁳󠁣󠁴󠁿
