It comes in a spray bottle and says to spray 3 applications on the first application. I just spray on one coat and spread it around with a eagle one tire swipe. I let it sit for an hour or so, then swipe them again. Wait overnight before the car drives off.
The tires were cleaned prior with Ef Hi Intensity full strength and a sponge. All this black and brown stuff came off the tire, yuck.
I let the tires dry, applied the AA like I stated in the first paragraph.
The tires came out if not the same shine as Ef Black Opal, a little less shiny, but still ghetto shiny for me, shinier than Vinylex.
The tires are 2 week old Firestone passenger tires. They are 15 inches, and I do not recall the name of them, but know they are Firestones.
I applied the tire dressing, went home for the week, we had some period of rain, and two weeks later, I inspected the car again. For sure there are water droplets on the car, but had no time to wash it. The next wash is this weekend if it is warm enough. This car is pretty good for the amount of care it is given and the odemeter is pretty high, roughly 57,000+ miles on it, a 99 corolla. The tires, not shiny, but a nice matte look. No browning.
As for Armour All degrading the tires, I do not really care. The tires are changed every 2 years. As soon as that 50,000 mile marker is hit (usually 2 years) the tires are changed. Now I do not use AA on the dash, it gets a nice diet of Vinylex. The dash is not likely to be replaced in the life of this car, that is much longer than 2 years.
So, I am not worried about the tires on this car. Now if it was a garage queen with less than 5,000 miles a year on 50,000 mile tires, then I will worry about the tire dressing. I would use a water base dressing most of the time, except for one car, a BMW 3 series in which I use Meguiars Endurance.
Well, after a few hours of doing paper work for new uniform issues, I am tired, so I will stop my babbling,
