I had this same situation, except it was a 15 year old car, more like washed 2-3 times rather than waxed that many (garaged, though), and a bit of a classic (a 1987 Buick Grand National with 23,000 miles on it). I wasn't the autopian at the time, so I didn't clay. I washed the car very thoroughly with GC wash. I then hand-applied Medallion Premium Paint Cleaner followed by #7 on one part of the hood, and Gold Class Clear Coat Prep and Swirl Remover on another part. The MPPC/#7 looked way way better. It was amazing how good the paint looked. So anyway, I did the MPPC/#7 route by hand on the whole car. I then followed up with Gold Class wax (which I didn't realize would strip the #7) and it really didn't hurt the appearance the way MPPP does after #7. It looked about the same after the GC as it did before it. The car looked amazing. It looked brand new except for some spots that had some serious chemical staining. There was a circle on the roof from a CB anntena that got water under the suction-cup and discolored the paint. I couldn't remove that either. Anyway, looking back, I would have changed the routine to include a claying and either dropping the #7 or following the #7 with a carnauba instead of GC.
