Thanks. I've read that the acrylic top coat that comes with the kit doesn't hold up as well as a more expensive top coat, but for the money you can't beat it.
I used the included degreaser and a wire brush, and also pressure washed it out a few times for prep. If I had to do it again I'd probably rent a floor grinder just to make it easier and get rid of the concrete imperfections, which the slate gray color kinda highlights. Gave it a day before...
