the classic trick is to use silicone lubricant, it rejuvenates the seals and prevents further cracks and damage. I use to use armor all, but it has very limited effects. In fact, I was surprised that when I bought the silicone lubricant, it even said that it was one of its purposes/function is to maintain and rejuvenate weather seals. The best is to spray that stuff and saturate your weather seals in it and leave it overnight until you wash your car.
armor all IMO should be applied as much as possible if you use it for this purpose. silicone lube, well I would think twice a month and the more critical places once a week, depending on conditions. I don't have a garage, if I did I would apply it less.
