I use mostly Meguires products now, I love the way they do. the first detail wash after winter i washed with dawn, then used a clay bar, then washed with regular car soap, then used Meguires ultimate compound, and Megs Carnauba Wax.
Dawn - ONLY use the blue ORIGIONAL. What this does is get all the old wax and road oils off the car.
Clay Bar - This (comes in a couple of meguires kits) is used to get small contaminants out of your clear coat. If you ever run your hand over your car and it feels rough, this takes care of that.
Meguires Ultimate Compound - There are many different types of rubbing compounds, this is just the one i chose. These are used for buffing out minor scratches, swirls, water spots, bird drop edgings etc. (generally only works with minor blemishes)
Clear coat sealant can be used to help fill in scratches some as well (though i have never used it).
Polish - Used basically the same way as polishing compound and wax this adds to the shine of your car.
Wax - There a different kinds of wax as well, each one works differently but all have the same general purpose: To protect your paint.
Since my life is starting to settle down now, the way my schedule will probably go is once a year i will:
Wash with Dawn
Wash with Car soap
Rubbing Compound (if needed)
Wash with car soap
and wash the car every week.
