Usually, what I'll do is after the kids have painted their cars, I'll take them and put a coat of clear coat on them. In the past, I've used this stuff: Aleen's Sealer

It works pretty well, but it is still an aerosol, which means that I have to be the one to do it, and it does create smelly fumes.
So, I'm thinking about getting a bottle of this stuff here: Pledge Floor Care Finish.

The product has been through a few name changes (In the video it's called Future Shine, I believe), but it appears to be an acrylic clear coat that can be applied with a brush.
Here's the video. Guys uses a little bit of salty language, so be warned if that's an issue.

So do you guys think it would work well as a clear coat over acrylic paint?
