If you're going to sharpen your knife on a stone before starting up a fresh whittling project, you lube it up with a couple drops of oil. This keeps the blade and the stone protected. Likewise, you'll want to slather a glob of rubber lubricant onto all the rubber components in your brake system to keep them healthy and supple for longer. And, the best source on the net for rubber lubricant is AutoAnything. Our digital shelves are stocked with premium rubber lubricants, and they all come with free shipping.
