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?

I have a saw sled made of 1/2" MDF also. No finish on it at all. It's
still going strong after 7 years. It lives in an unheated garage in
Seattle. Unless you work in the rain, don't worry about it.

Me, too. More stable than hardwood in those conditions.
