My last camry developed a lot of flaked off clearcoat on the hood and roof segment. I want to prevent this from happening again with the newer camry which is constantly outside in the elements. but I'm not somebody with the time or desire to scrupulously clay and wax my vehicle every other week. I'd like something that can easily be slapped on and protect the clearcoat and last a very long time. About the easiest thing I see is those automatic carwashes that offer wax as one of their superpremium options but I'm guessing this might not be the best way. Does anyone have any suggestions?
