It's ok. I use Meguiar's Natural Shine because it looks good without being too shiny. It lasts a long time and I've used it to make some rough looking spots like new. Megs also has the shinier version if that's what you like but I haven't tried it.
The consensus is it's crap. Try VLR or 303 Aerospace Protectant which is becoming more widely available. Both will leave a less glossy, less sticky finish.
I actually like Armor All for certain things. The old school Formula 2001 was my fave,but the formula changed when it went to Formula F21. 303 was the absolute worst one of all I've tried. Years ago I stopped using vinyl and plastic "protectants" and started using leather conditioner on all interior plastics and love the long term results.
ArmorAll does not protect very well. It leaves a oily film that attracts dust and dirt and also creates a shiny surface which is not good for interiors as it creates glare and reflections.
303 is the best thing I've used on the interior. Adds a darker, rich look to all interior materials without making them look greasy. Armor All was the '70s and 80's solution. I use it to clean and shine fender well liners when I have the wheels off, and that's about it.
silicone products like AA cause breakdown of plastics, which can be seen by the haze formed on the inside of the windshield. The application of a silicone product to interior plastics therefore may look appealing but also degrades what it's applied to.
