I'm in the process of getting my car ready for another season of snow and slushy salt in the rust belt. Back in the spring I changed my usual routine of just waxing the car over the summer months due to the fact I knew I would have no time as in previous years to detail throughout the summer. I applied a layer of AIO + two coats of SG + 845 back in April to coat the car over the summer. We are now 7 months later and I want to give the car a fresh protective coating to last the winter. My winter routine has always been Klasse AIO + 3x coats of SG and then a wax, but in past years by the time summer comes to an end usually any remnants of Klasse have worn off the car. Will AIO remove the old Klasse coatings or do I have to use a polish with my DA machine to accomplish that?
