I would have to say that I love how the Rain X or Mother California Gold car wash soap works on my tc. They both really bring out the deep black look on the car and it always looks like it was waxed.
For wax on the other hand I would either go with Rain X's spray on wipe off wax or if you are in to the buffer and wax thing that I would go with Mothers Cleaner Carnuba Wax. Both give a baby soft paint feel and I love how they come off with no ugly smearing or left overs. Just my two cents.
I have used practically everything out there that is on the shelf and I have found those two to be the best....
For the Dash and Windows I use Stoners Invisible Glass and Stoners Trim Shine. The trim shine is not too glossy and gets rid of dust and dirt while shining in the process.
I personally like the K.I.T. car wash myself. I know of a lot of detailers thet swear by it and it never took that nice coating off of my paint when I had my suburban. It's also Carnauba based and comes in generous quantities. Save yourself the loot.
