I use the Turtle Wax Ice for detailing 2 or 3 times a week, and my car looks great. I wash it fully every week, then detail it after.
Should I also be using an actual WAX or other sealant as well? For summertime, the Ice seems to be doing great on its own, (when I wash the car, I can barelty see a difference- I do it mainly to get every last bug off the bumper...

) but when the weather gets icky I know the car will get far grimier with road salt and such...
I plan to get a clay bar over the winter and do an annual or semi-annnual claying in the Spring/Fall for shine, but I wonder if I should be doing somethig a bit less involved but still more than Detail Spraying between clayings?
Thanks!
