Query: Eats up pin rubber boots

I completely agree with other posts suggesting this grease eats up rubber boots that cover caliper pins.I used this product over years and I had to buy replacement boots until I stopped using it. Boots get soft and spongy until they completely come off the caliper pin seats due to rubber degradation. Not sure where you would use this product if not on pins???
