It's sure better than nothing...you need something to put a film on
the rubber so it doesn't dry out so soon or be so vulnerable to ozone

You just need to apply silicone SPRAY more often than a grease
coating...whenever you're under the car doing something, use the
silicone spray on rubber boots, bushings, etc.
