I just made a table saw sled using 1/2" MDF for the base.

MDF is very prone to expansion from moisture. I have some Minwax Polyurethane.
Suitable to seal the MDF? Just around the edges, or all surfaces?

Shellac, right out of the can, works well also. It's what I use, but I
usually have some used tins laying around.

Johnson's Paste Wax will also work and is much slicker than either poly
or shellac, unless you wax them.
