Dear Olmanmark,
The products I use are not available to the public. With that said, I think Wolverines products are as close to what I use that any other DIY kits out. I have never used them, but from some pics and comments from users, its probably the best bet.
You should really worry more about the preperation of your concrete than the material itself. Example, I can use cheap products on a well prepped floor and it would last longer that the best unobtanium products out over a ill prepped floor.
Remember, with prooducts, you usually get what you pay for. With preperation, there is no shortcut. Diamond grind or shotblast and vac it up good.
Good Luck
