I have been using these products exclusively on my cars since about 2002-2003. I used it on my MDX, Touareg, Speed6, CX-7 and now CX-5. Oddly I get the most compliments on the T-reg but I also put the most layers on it.

However, you do have to order online unless you live in NJ.
Their exterior products make you car 'glow' especially at night under artificial lighting. They take some time to apply and the more layers you apply the better it looks and lasts. The UV protection alone in the products is worth its weight in gold. When I traded in my 2008 CX-7 the sales manager actually said my car looked amazing.Those guys are getting paid to say your car looks horrible so I took that as a win for Zaino. Their products also kept the headlights on the CX-7 from turning hazy/yellow.
I use their exterior products and their leather conditioner.
I start with this:

Then a layer of this:

I then alternate between the two until I grow tired then I finish with this:

I put all the products on everything- wheels, headlights, black plastic trim, and anything that will see sun. It leaves no residues and once you are setup you don't need to reapply for a long time (depending on where you live of course) I am in a rain free, snow free, sun all the time local). In fact you could just hit the car with a clay bar if needed every 6 months or so and just put another layer of clear seal.
I finally got one of my brothers to start using the clear seal as he normally does nothing and his car ends up looking like crap after a few years of exterior abuse. I figured if he at least does the clear seal twice a year on his new ride it will be a big improvement.
I bet if you do some searching on the web you find reviews and can make an informed decision.
