I'm an asshole, I got tiles for free. Egan was tearing down a datacenter so I have a garage floor made of black non-skid antistatic 2x2 grids. Works well, cleans up well, and the seams are tight enough that there's not much of a liquid problem. I'll probably raise up a strip every few months and let it breathe just in case, though. I like 'em becuase I don't have to worry about tires pulling them up. Mops up nicely.
I'm just glad to hear you have your garage going
