I just bought two new Subarus for my wife and myself and want to learn all I can about car care. Thought this would be a good place to learn. Since the cars were detailed before I got them a couple of weeks ago and the paint is in great shape.. just curious what I should use wax/sealant wise to maintain a nice appearance? And how often should I apply? We have a lot of bugs and heat here that I need extra protection from and my cars are silver. Thanks! Chris
