Floor Coatings Questions

I have done two garages now. Several years back after completing construction of a detached garage I used a pricey two part epoxy. It was a total bust. The concrete had cured maybe six months when I put it down, maybe that wasn't long enough. Stuff started peeling up within a couple years and is pretty much all gone now. I followed the directions to a tee, but it didn't last.
A couple months ago I had our attached garage floor done by a company that came in, ground the surface off and put it down. This was some "new" to the market, polyaspartic I think it was called. Used on bridges and stuff (they say) and comes with a lifetime warranty. Supposed to be able to park a car with hot tires on it with no issues. It really does look nice, although as said in an earlier post - finding a screw or something dropped is near impossible! I watched several you tube videos to see if I wanted to do it myself - it would have been a big job doing it alone, and grinding the surface down - an acid etch doesn't take it down far enough. They also ground out a couple cracks and used a seam sealer to refill. They did a great job - and a whole lot different than the you tube videos I watched.

Rob, hit me up if you want the name of the company. I can't speak to long term yet obviously, but I am pretty confident that we are good to go here.
