I have now learned more about shop floor coatings than I ever wanted to know.

Thing is, I think I've figured out the best solution for me. If you want one of the hard epoxy like coatings to "adhere" to your concrete properly...you need to open up the pores of the concrete which means grinding...which means money. Once you have it open your choices depend on how smooth you want it to be once done. To get super slick and glossy, you need to grind it smoother (like wetsanding paint).

If not that worried about smooth looking, you can just clear it and be done. The acrylic clear quoted to me in the $2.50 per foot option above is not really recommended for auto shop uses though, it doesn't play nice with liquids that stain. We have decided to go with a Polyaspartic clear on top of the 80 grit ground concrete which will give the floor an epoxy like protection but in clear so it can be touched up if needed. Should be smooth enough to sweep up with a dust mop as well.
