I subsequently also glued some drawer liner on the top surface so I could use the work surface without scratching the paint.
I am puzzled by the lack of any kind of stay for the top. And it doesn't seem to have ever been fitted with one. I'd like to put a gas strut or struts on it but I don't want to drill any holes in it. I attached a Harbor Freight magnetic tool bar by drilling an extra hole in the bar and lining it up with the holes already in the top brace. I also added a Harbor Freight magnetic spray can rack which fits perfectly.
