When I drive at night or before dawn (when the humidity is worst), running the A/C, my windshield fogs. Not on the inside, the defogger handles that, but on the outside, so that I continually have to use the wipers. This was true on my previous cars driven here as well. Would a regular application of Rain-X help keep that fog from forming?
Having used both and having the same problem living near lake Ontario where I encounter the same conditions at this time of year I can tell you that the Aquapel will drastically cut down on this but the Rain-X will not.
If you set the heat controls to highest heat setting on the window defogger with the fan on medium to high setting for the first couple of minutes until it warms the windshield and then lower the temperature to where you want it in the car and change over to the vents and not the defogger, it will fix your problem without these products.
I stopped using the products because it's too costly for me to keep re-applying and I do so much driving that they wear off sooner than they would for the average driver so I have compensated using the defogger set to heat initially and then change to vents and then lower the temperature to what I want the cabin at.
The idea of setting the defogger, even briefly, to "heat" during this rancidly hot and humid summer is enough to make my skin break out. Perhaps I'll try it, though. Like you, I really don't want to be re-applying the stuff to the glass, and I'm not sure where I would find Aquapel around here anway.
