What paint would be suitable for a workbench top? My garage workbench has a chipboard top and when it started looking a bit dirty and rubbish I just picked up some slate grey emulsion paint, now I know its not the hardest wearing coating but its done alright. That was about 5-6 years ago and it needs another going over but the little bit that was left in the tin had gone solid, so before I buy some more, is there something better I could use thats slightly harder wearing and perhaps wipable if a drop of something gets spilt on it? Ideally available in slate grey if possible
