Please tell your husband (and he'll argue with you, cause he'll tell you "he's always done it that way"), not to use regular Armor All on tires. I see the damages from it every week.
Tires have a built-in anti-oxident in the rubber that migrates to the outer surface to form a barrier against ozone and such. When people apply a lot of these tire dressings and such, they are actually removing the anti-oxident barrier....and inadvertently causing what they are trying to prevent. We call this anti-oxident migration, "blooming".
Here is an excerpt from Bridgestones site (and just about all tire manufacturers will say the same thing) about this:
What’s the problem with oxidation?
Oxygen, like UV light, can break down rubber molecules, making rubber brittle, causing cracks, and rapid wear. Oxygen in the air can cause this, and ozone, a special type of oxygen molecule, is especially hard on tires. So, we add antioxidants and antiozonants.
These are special chemical compounds that help prevent those tiny cracks you sometimes see in the sidewalls of tires. And by the way, here’s a tip: Avoid washing tires too much, and especially avoid putting compounds on the sidewalls to make them shine.
The waxes, antioxidants and antiozonants are designed to protect the surface of the tire, and by cleaning them off, you’re removing that protection, causing tires to age prematurely.

And here is Dunlops statement:
Can I use sidewall protectants or cleaners on my tires?
No, you should never use protectants, cleaners or dressings on your tire sidewalls. These may degrade rubber and remove the inherent ozone cracking and weather checking resistance put into the rubber by the tire manufacturer.
Use a mild soap solution to clean your sidewalls, white striping or lettering, and rinse off with plain water.
It's best just to use soap and water to clean your tires off, then let the anti-oxidents in the rubber do their job.
