Ron, you've gotten some good advice here already and chief among those is the clay bar. It will do wonders for prepping the finish for your wax application. Without removing the bonded contaminants that clay is designed to remove, you're basically just waxing dirt that is stuck to your paint. Nobody I know of makes a wax for dirt. Nobody.
Just about everybody here knows that I work for Meguiar's, but they also know I'm wide open to folk using what ever product line they happen to like. There's a lot of really good stuff on the market and, quite frankly, how you use a product is at least as important as the product itself. The best stuff on earth isn't worth diddly if you don't use it right.
You might want to check out Meguiar's forum at
Meguiar's Online and specifically read through our 5 Step Paint Care Cycle. It will outline what needs to be looked at (only you can really evaluate and determine what needs to be done to your car) and even make product recommendations for you.
The G100 buffer you have is going to be your best friend. Pick up a few new pads, some Meguiar's Ultimate Compound and some NXT Tech Wax 2.0 (or Adam's, Zaino, Mother's, whatever you like) and have at it.
