Hi, I removed a dishwasher that had a wooden countertop surface.  I am going to put my mini-fridge there and just a wooden insert for a countertop and decoupage vintage kitchen ads from some old mags I got from the attic.  Now my question is this.  Could someone tell me the name of a finish I can use over my decoupaged ads that will protect them, in other words render the surface waterproof? I hope I inserted this question correctly, this is my first time on line.
