Yep, I just painted mine with some leftover porch & patio paint. Looks nice (glossy), more durable than the usual latex paint, super easy to wipe off. Most importantly, very easy to touch up because I'm not worried about having a perfect finish. If it's a little off, that's ok--it's a garage workbench, not fine furniture.
I also decided to go one step further and cut some vinyl-backed masonite board and screwed it to the top. If that gets messy enough eventually, will just replace. Overboard, yeah sorta.....but this is the garage journal after all. Nothing is overboard around here!
