I wonder if there's a protectant you can wipe on the boots, say twice a year to keep
them supple so they won't crack for the rest of the life of the car!
I'm gonna look at my half shaft boots when I pull the brakes in a week or so!
Yeah there is. It's called "silicone spray". It comes as an aerosol and in a solid form in a tube. Simply slather some on a couple of times a year and your set! Also works great on weather stripping, and anything that's rubber that you want to protect/moisturize.
