You probably have already finished your bar, but heres a suggestion. I have a new bar that opened up in town. Its called the Engine room. This guy who owns it made a really cool looking bar and tables. He actually poured a mortar, concrete mixture for the top, about three inches thick. while the concrete was still wet, he pushed all kinds of old wrenches, bolts, large sprockes, nuts, washers, ect and let them sink into the mix. He then covered the top with about 3/8″ of Envirotex, or some other Epoxy. Looks really neat. ‘The cement mixture turned kind of whiteish grey and looks great. Hope this helps.
