I trust Legacy and GF and they have a good point that a water epoxy isn't the best. If you can afford it go that route.

Even tho it isn't "that much more money" sometimes it's just not in the budget. When I did our garage we had just bought the house, gotten married, and we had not leased my condo out yet. Additionally, contrary to my hopes the tree in the side yard was not a money tree.... just a really tall Persimmons.
I wanted to be able to put my stuff in the garage, and get things moving. The floor had been painted at some point in its past with brown latex wall paint.... as you can imagine, it was a mess. We went with the Seal Crete Epoxy and Clear. I power washed and patched the floor as best as I could, and then prepped it per the directions. For a 480 sqf garage all my materials cost under $125. Prepped and let it sit for a week. Laid a 1st coat, a second coat with chips, and a clear coat. I bought all supplies at Lowes, except for the flakes that were someone elses surplus that I bought on EBay.... Gray, Black, Light Blue, and Glitter
One problem was about an hour after getting the first coat applied it started to rain. This corner by the garage door where there was splash from the rain has been the only place we have had any issues with the floor. The paint peeled up a bit, but I am CERTAIN it was due to the extra moisture when we put it down. After almost a year, we have had no problems other than that one corner.
Here is a picture I just took 10 minutes ago.
If I had of had the funds when we moved in I would have loved a full epoxy. But I don't think (as of yet) that my choice was a bad one. Time will tell.
Oh, and as you can see, I have taken the precaution of parking on mats just in case. I saw many horror stories about lifting, and figured why tempt fate. They are just Harbor Freight Anti-Fatigue mats. One bonus is when the car is wet, it collects most of the moisture. If I am working in the garage, it takes 10 seconds to lift them up and move them, and another 10 seconds to plop them back down when I am done. I drew 2 little "L" shaped brackets on the floor around each mat with a sharpie so it is really easy to place them back down in the right spot. I also have a drop down globe parking stop aid for my wife that I made.
