Thanks. My adult BPs are kinda skittish about being 'watched' when they eat, so I put in the shade so I could pull it down over each tub as I fed them.

The stuff covering the undersides of the shelves is plastic sheeting. I probably could have used contact paper, but the plastic seemed stronger. I used poly-based wood glue to attach it to the underside of the shelf, then secured the edges with staples on the other side...away from the snakes. The whole rack is painted with Rust-Oleum 'Gloss White' Latex base paint - moisture resistant.
