I'm building some shelves in my shop based on the Woodsmith lumber rack.
P1020902.JPG (Lumber rack I've already built. For the shelves the arms will be a bit longer).
For each level, I'll cut a plywood shelf with slots to fit around the arms. What would be a good , tough, and inexpensive finish for these shelves? It's for the shop, so I'm not making any fashion statements, just looking for protection (and nothing that will stick to the stuff sitting on the shelves).
Thanks!
