BJ007 - Is Behr's acid etch muriatic acid?
According to Rust-Oleum's instructions it states-
Note: Do not use muriatic acid.
I wonder if they state this from a health perspective. Muriatic acid is some pretty nasty stuff. It looks like they could be suggesting to use their cleaner only since it is a mild citric acid.

Thanks for the tip about the chips.

paul34 - I am not certain that using a primer would be beneficial. This garage floor coating is made to be painted directly onto concrete. I would think using a primer may cause more of an issue because if the primer gives then the coating will more than likely come up in that spot anyway.
