Did mine myself 3 years ago. Used the Home depot stuff. Was pretty easy, floor to this date looks great. Key is to make sure the floor is clean with the acid wash. Here's a tip - If you use your garage for wrenching or working on your bikes or car for that matter, forget the flakes. They look good if all you do is park a car in the garage. If you are wrenching on a car or bike and drop a smallish nut, bolt or wsher, it will be almost imossible to find on the floor. The bolt will blend in with the flakes and will be hard to see. Trust me on this, I "flaked" my floor, and like everyone who has worked on a bike have dropped a scfew or two. I fiinally bought a large magnet from harbor freight.
