I used to own a car wash so I have tons of leftover HD chemicals of all kinds. I use leftover TP-21 detergent...one small cap full per gallon, works GREAT. You can read up on it here if you're bored and have nothing else better to do Transchem - Transpak Concentrated Carwash Products
I prefer Meguiars for their tire shine products. I like the gel with the sponge applicator. So far it lasts the longest from all that I've tried.
For wax. It's Mothers brand all the way. Turtle wax is good for the boat/jet ski. For my vehicles I just use Mothers wax system. Not all three steps (I'm too lazy for that), just two if my back can handle it and the weather holds out long enough.
