I absolutely love the Chemical Guys Butter Wet Wax. True to its name, it just melts into the paint like butter. And it lasts somewhat longer than a lot of the other (i.e. more expensive) waxes I've used over the years. When done right, and with a little elbow grease, I can spray the hose on the hood and all the water just falls right off and it's dry to the touch.
For wash soap, I avoid anything that has wax it. It messes up the black trim. No sense buying expensive stuff when it's all in how you wash it. Usually I make do with the cheap Simoniz/Turtle Wax stuff I pick up on sale at Canadian Tire. Meguiars makes a nice wax-free wash soap, Sonax does too, and so does Chemical Guys (Mr. Pink.) but their regular price is too much for me.
Tires I just use Spray 9 and whatever wash soap I have left in the bucket and scrub the hell out of them with a brush. Then I use the Chemical Guys Silk Shine on a microfibre cloth. I don't like the glossy/wet look on tires, and Silk Shine has a nice matte finish that usually lasts a pretty long time. I'm not normally a fan of those spray-on-and-leave tire cleaners/dressing, but that Black Magic stuff you see at Walmart is pretty good stuff to use if you just want a quick matte finish.
Interior I like the Mothers leather cleaner/protector. It seems to be the least-greasy of all the ones I've tried and is reasonably priced. It also seems to be the longest lasting as the leather will squeak as you sit down for a couple months after cleaning. Dash cleaner I like the Sonax brand. It has a nice matte finish and lasts a very long time before it starts to look dull again.
