I think we discussed using Armor All several years ago and so some of this may be old news to many, but . . . Here's the latest story I've heard about it. This comes from a guy who does detailing at a local dearlership. He claims that Armor All will ruin your top or your dash for the following reason: it coats the surface of the top or the dash with silicon molecules, which are round (according to him - I've never seen one close up) and act like millions of tiny little magnifying glasses on your top. In other words, they concentrate the light and the heat and actually accelerate the expansion & contraction that goes on when a car is out in the sun and then in the dark, etc. This expansion & contraction causes it crack faster. I think this sounds plausible, but . . . expansion & contraction of vinyl is going to occur regardless of whether or not you have silicon (or silicone?) on it. I don't really see how that can "accelerate" the cracking. And I would rather have something on it that had some sort of UV blocker in it than nothing. Second, I remember, from YEARS ago, when these products first came out, that they did an awful lot of testing. I can't imagine that they didn't discover this problem when they created this product, some 30 years ago . . . (I think it's been that long) . . . or maybe they're just scamming us? I don't use Armor All, but I use other vinyl protectants. Right now I'm using Meguiars. I will tell you in 15 years or so how it works . . .
