Water-proofing mdf??

[cbmar]

I bought a table/bar at Spirit's after Halloween sale. The wood portion of it appears to be made of MDF. Can anyone suggest how I can treat it so it can be left outside in the elements at Halloween time? I'm worried that even if I somehow paint it with a waterproofing laquer the moisture will still seep in and wreck it. Ideas?

Try something like spar/marine varnish...

I second the vote on a good marine varnish. Two or three coats and dont forget to do the edges really well.
