It will undoubtedly affect the Aquapel, but whether it completely removes it is a good question.
You would need to strip the Aquapel to get the max benefit out of this product or any other windshield treatment.
Just a quick question: if you already have Aquapel, do you really need this product as well? I was under the impression that any at least semi-quality windshield treatment would make ice removal a bit easier.
Of course, I am a typical "snow is a myth" Floridian, so maybe I don't know anything
And yes, with any spray product, its always a good idea to spray the towel and not the surface.
