Upon reading here and other forums I am under the impression that every year or twice a year you are suppose to decontaminate and clay bar the car either once or twice a year depending on where you live I assume. Well with a coating applied to your car what sort of maintenance do you guys do or is the coating that good where tar and iron deposits don't stick to the panels and wipe right off with a normal wash. Thanks live in the Northeast and of course the winters might be a little rough so might not be able to do a regular maintenance wash every week or every other week. Thanks for your replies
