I have used polyurethane to seal the MDF on my drill press table and out feed table. A few coats helps keep glue and paint from sticking and from water causing stains or bulging. It is also very easy to refinish if you need to keep that like new look.

The laminate on my router table is smooth but the edges are chipped and it it is dirty from years of use.

Another tip, keep a few inches of over hang on each side of the table for clamps. I did not leave enough and the tee slots are not always in the best spot for what i need.
