I just bought a new car, and it has a protected/sealed paintjob. The Salesman said I don't NEED to wax or polish it, however I am wondering if I CAN. I don't want to ruin the sealant that was put on the paint, however I do want the mirror finish that a polish/wax can give. Are there any special polishes I can use (that are available in Canada) on this to not ruin the protectant? Thanks.
