I use Meguiars consumer line (it's easier to find, plus I found mostly it works better for me for some reason than the professional line). Paint: First, Step 1 paint cleaner (if your paint feels rough, claybar too), then step 2 polish, followed by Gold Class paste wax (paste being my personal preference). I use Westley's tire cleaner, Meguiars Hot Rims wheel cleaner, and Meguiars gel tire dressing for the rires/rims. I have Quik Detailer for touch ups (damn birds). My car isn't a DD, and it's garage kept, so that helps keep the paint in good shape, but the previous steps really made the color "pop", imo (bought the car used-it was an ex-rental, so I'm sure it got the quick wash/dry, no real paint care before I bought it).
