I personally really like the detailer. As opposed to Meguiar's Ultimate Quick Detailer, this one wiped the dust of the car very easily, while UQD sometimes left behind some of the dust. I also love the smell of it. I am going to use the ICE detailer from now on.
As for the polish, it's actually a wax. I've seen great results with it and it is very easy to use. It also cuts down on the time you have to wax. What's best about it is that it doesn't leave ANY residue and you can use it on vinyl.
I can't account for the car wash or the liquid clay bar. It has worked for some people, and for some it didn't even remove tree sap, etc. I'm betting the results you can get with it depends on the kind of paint on the car, since it works for some and it doesn't for others.
Overall, I really like ICE even though it doesn't last more than about 2 weeks. It's convenient for me since I like detailing and doing stuff to cars frequently so I can live with the durability of the polish. Plus, if you get the liquid polish, you can really get a lot out of it since you don't use much to polish a whole car. You can probably top it off with your favorite wax like NXT. Of course a lot of people on here are biased and will turn it down because they order their good products online and there will always be something better, it's just a matter of preference and situation. the ICE line is a very good OTC product for people who don't want to spend as much time waxing or who don't want to wait until the products they ordered online arrive.
