 Absolutely. In or outside. I'm not fond of the taste of that stuff either, to be honest with you. No. Right. And, Mark, I've used it. I have quite a few collector vehicles, and I've used it on my cars. It will sit sometimes for seven, eight months. And what's nice about it, you don't have to come out. You could actually go to NHLU's site and order an aerosol can. So if you have troubled areas that you're concerned about, you can apply it yourself.
