First off, what is it? Basically its an acrylic gloss medium that meant to coat furniture but works amazingly well for hobby purposes. It goes on easily in from an airbrush or regular brush. You can use it for general gloss coats, protecting layers underneath when using oil paints, or using it as a base for decals to prevent silvering. With oils the key thing is that its acrylic based, so thinners won't eat through it. This is important if you're doing an oil wash and rubbing it off later because a regular gloss spray is oil based and will dissolve with your wash.
I think I first found out the name changed in a model train magazine, so when I saw this in Walmart I knew it was really Future floor polish in disguise. Here's a few pictures of the bottle I have. It was purchased a few years ago in Canada, but I believe its the same thing in the USA.
