you really need to know how to use the machine. first this is really hard to make sure the surface is clean. u can use your hand to feel it after u wash your car, u will still feel the surface is not smooth, feel like lot of send stick on the surface. if the surface is not clean enough, the machine will damage the top clear coat or even to the top layer of the paint.
second, use the right wax and applier. some wax will dry very quick and become a crystal/ power then scratch the surface. u need to know when u have to stop and adjust the speed. otherwise. u just damage your paint. even worst then u dont use.
u better dont touch it.
