I also find this amusing. I don't see how applying another layer of clear (if done properly) can be cost effective. A good detailer will measure your paint prior to any heavy compounding. A good 2 step correction/polishing process will run about $500-$800 from a reputable detailer (depending on the market). What sort of paint job even if it is just clear can you get for that??? To paint anything requires prep work and sanding (before and after). I am sure you don't want your paint to look like an orange peel. Right?
