Dozens of sprays on the market. Many with "SILICONE" plastered on the cans but mostly petroleum inside the can. What product works best for keeping our Honda CV boots from drying up and busting open?

if you want something that is silicone w/o petroleum, i would guess anything labeled "food grade" would fit the bill.

Thanks. I just went ahead and sprung for a can of 3M Silicone Paste. It's non petroleum. I figure I'll be using it twice a year on the CV joint boots plus it is good for o-rings of all types, including the ones on injectors. Will wipe a little on the rubber door seals and weatherstripping, etc. Kind of done with using petroleum based stuff. It just evaporates and causes a drying effect.
