 Well, we actually are using, we're trying a hybrid product out for them on our own truck, which is kind of a little of both. And we're going to go back and see because, like I said, it's an older vehicle that already has started to get some surface rust under the body. But the oil is, like I said, it's going to creep and it's going to coat and it's going to get into those areas. And typically the oil I'm going to be using on the body where it's going to get up into those seams and continue to creep.
