Just something you might want to think about...You may want to go with the basement epoxy application rather than the garage epoxy. We used an epoxy last year on our garage, prepped it really good and everything...but now a year later there are spots where it has lifted up and is showing wear. Amazing though a spot where I used just regular basement epoxy rather than the garage epoxy..it is holding up just fine.

When I find the time I am going to strip off the epoxy I have on now and apply the basement epoxy to the entire garage. Good luck!
