Fully agree with this. Anyone who has not done a full prep doesnt know what they are missing. For the effort of stripping it back twice a year (wash, clay, polish, wax), you are rewarded with not only a beautiful looking car, but also a much easier to maintain finish. When you have glass like paint, protected with a decent wax like DD SN, and topped up with something like Red Mist regularly (every other wash), it means the crap never sicks to it, so washing it becomes a breeze, much easier than a car that hasnt been prepped. You only need to do a full prep twice a year at most, so its not really any extra effort for a much better looking car
