I would like to paint my garage floor 2-1/2 car garage. It was repainted many years ago( we moved in 1993 and previous owner painted it.) It is currently light grey. Thereare some areas mainly in the tire tracks where that the paint has peeled off. I am not sure what to use. Not sure if epoxy will adhere to the painted areas. I dont want to spend for epoxy paint and have it come up. Do they still make oil based paint anywhere? Any ideas
