I built my first reloading bench in 1977 with a 5/8 inch thick plywood top that was part of the structure.
In 1995, I built a reloading bench where the dimensional timber carried all the loads and the 11/32" thick waferboard top was there because I couldn't get reloading components to levitate.
For both, I finished them with a single coat of a quality polyurethane varnish. No static electricity problems, no clean-up problems with either. They're both in service and both approaches to the work surface have worked just about equally well.
