I have been using armor all products for years with no ill affects. It's like any product, you have to follow the directions. It's not supposed to be gooped on and left there. It's designed to be applied, let sit for a few minutes and wiped off. I've owned my Imperial for 23 years, and it still has all it's original interior panels and they are in great shape. I don't use it on leather, I use Mothers leather lotion for that. I also don't use armor all on exterior surfaces, and certainly not on tires. 300ly, Don [Non-text portions of this message have been removed]
