For years, I've covered the top of my work bench with 1/4 fiber hard board the same stuff that you use as a pegboard for hanging tools but solid without the holes. It will last me years & cleans up easy. Now & then I get an oil spill or paint on it but when that happens, I just wipe it down. And silly as it sounds, all those oil & paint stains give it character. But when it gets too bad, I simply unscrew it from the bench top & put a new one on.
Aside from a metal top covering for a work bench, is anyone using anything like mine or a different material & how long does it last? I've only had to change my fiberboard top two times in the last thirty years.
