Refinishing Garage Floors

I've got to spend some time this weekend helping my Grandpa in his basement garage. Awhile back he mentioned that he had found some concrete paint stuff that he wanted to use in the basement garage to make it look nicer. I have a feeling my Grandma is really the one behind the whole mess because my Grandpa really doesn't care what the garage looks like. Tomorrow hubby and I are going to spend some time helping him clean out the garage, then I guess they'll pick up the paint and finish the job in the next couple of weeks. Honestly I wish I could convince him to redo the floor in our garage, too, but cleaning out and painting both garage floors would take a lot of work because my Grandma uses our garage for storage. Ours is stained with oil from years of car rebuilds, but I probably won't get lucky enough to convince them to do it. Oh well, it's always nice to dream isn't it?
