Over time a car can easily get small scratches from people passing by and accidently catching the car, a slight scrap in a car park or even simply from washing. Scratches can age a car quickly and can knock money off the value of it when you come to sell it. There are protection packs that you can put on the paintwork of the car to try and avoid the small scratches but if you do get them there are things you can do to remove them.
Provided the scratches are not that deep, then a simple solution like T-Cut can be rubbed in to the paint and buffed out. For an all over better finish that will leave your car gleaming, you can use a car mop that is an electric buffer. This can be used all over the car to give it that showroom look but must be used with car to avoid damaging the paint.
