Garage Floor Coating Opinions

I'm afraid of it lifting but I guess I could live with some defects after 4 years. Thanks for the acid stain idea, might have to use that on other parts of the house. This garage project doesn't seem to want to end, we just found about a 10x6 area behind a wall, so we are going to open that up for more storage!

Here is another pic with molding of the server/storage room.
