I agree with this, and NOW is the time to do it while the floors are still clear of clutter, it isn't actually that hard to do, ive done a few now, I just used the Dupont kit from home depot it either comes in one or two gallon kits depending on the garage being a double or single, simply clean the floors really well with top and I believe the kit has a acid wash kit in it. Scrub it in, rinse it off and let it dry, the paint has a curing agent you add to the gallon, mix it, poor in a tray and use a long broom handle and roller and roll it on. Stop every few feet and toss on some sprinkles that come in the kit, they add a little pasazz and grip then keep going till it's covered, let dry a couple days and enjoy! As mentioned above it sure makes oil and A/F spills easy to clean AND brightens the shop!
