My junker workbench is bare plywood stained with Hoppe's, WD40, finely ground specs of smokeless powder, all manner of lube oils and residue where I sprayed the gunk out of guns with carburetor cleaner etc. Have also overhauled carburetors, worked on chain saws, and whatever else had to be done. Let's just say it's a "natural finish" which is a result of what naturally would happen during those activities.
