I always take their pads. They have three small silicone balls that ensure a good seal. I'm not sure if you need to use them more than once, but I do. I smeared it with oil (gear grease if it's for a differential, ATF for the gear covers, etc.) and applied it. They're a little pricey, but better than cork and more durable than other pads I've used.
